I guess you have installed the operating systems in the wrong order. Windows will carelessly overwrite the boot sector. Please see this Boot Repair tutorial. That should do the trick.

Try to locate and mount the Windows partition first, then run sudo update-grub. For example, sudo fdisk -l results /dev/sda1 2048 53035007 53032960 25.3G 83 Linux /dev/sda2 53035008 99139583 46104576 22G 83 Linux /dev/sda3 99139584 141266943 42127360 20.1G 83 Linux /dev/sda4 * 141266944 215681023 74414080 35.5G 7 ...

I believe I know what the problem is, and I can tell you how to fix this without deleting or reinstalling Windows. I've run into this problem twice and fixed it both times with this method. You see, prior to EFI/UEFI, there was a grandfathered-in limit of how many partitions any drive was permitted to have. I seem to recall the limit is three, or is it ...

I would suggest you to install ubuntu on a virtual machine and get use to it. Once you feel comfortable using ubuntu make the partition of your disk or even better reboot your computer with only ubuntu :D https://www.virtualbox.org/ http://www.ubuntu.com/ Hope that helps

Something is confused here. You do not need this "Reserved BIOS Area" Normally. A 1Mb empty space is normally created before or after partitions because of partition padding, it has nothing to do with booting. Are you using MBR or GPT partition table? It should be GPT. Is the medium you are trying to install from, UEFI-compatible and is it actually ...

My advice is to download this boot repair iso and burn it to a CD-Rom then boot to it and run the Boot Repair utility. Be sure to copy down the boot-repair url when you get the report so in case it does not work, you can post the URL here and one of us can analyze it for you. My previous answer, which was nearly identical to this one was deleted by "Mitch" ...

Why dont u try to run boot repair from windows 10 iso. That way windows will have an MBR and it would show the other Operating systems. Try that.

I've seen a few partition edits go wrong and fixed them (without loss of data) a couple of way, but I had still backed up all data first just in case, even though it turned out I didn't need the backup. That said, I've never seen gparted go that far wrong. I can only imagine that there was a power interruption while it was working. I will make a few ...

I will try to answer my own question. Apologies if my use of technical terminology is wrong. Aim: To get Ubuntu to boot as default, and allow me to boot Windows by playing with BIOS. I believe the problem is the EFI on my machine does not allow me to boot from anything but /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi, see here for a discussion of this. The ...

As far as I have heard, dual booting (Ubuntu and Windows) in UEFI isn't very clean I need to reinstall it to get it in CSM. This is not true. As @RodSmith already said, there are firmware bugs or seemingly deliberate faulty implementations. The device manufacturers are to blame for this, not Microsoft! (If you're blaming Microsoft and do nothing ...

I have never used/installed win8, so the following may not be the right way to go in your particular case. Having said that, I just did a win7 + 8 Linux distros (Kubuntu, Trisquel, Puppy, Slitaz, Arch, Slackware, Dragora, Kali) multi boot in a laptop with 160 gb in HDD with 1 common swap partition for all Linux distros and 1 partition for data, and another ...

it is a bug.if you are installing using pendrive just modify the filename "grub-efi-amd64-signed_1.9~ubuntu12.04.4+1.99-21ubuntu3.10_amd.deb" in directory /pool/main/g/grub2-signed/ by adding 64 at last before ".deb".works 1000%

If you have successfully installed Windows 7 with UEFI then everything should be in place. You would just need to boot the Ubuntu media the same way for installation and it should provide you the install alongside option. 1) Will I lose much functionality or efficiency if I simply switch the bios to legacy and do everything that way, which seems to be ...

If this were a desktop as opposed to a laptop, and you don't specify, I might advise cloning the partitions to separate hard drives and literally switching off the drive you don't wish accessed. That's what I'd do. UPDATE: I found the answer ON THIS SITE It is entirely possible to get exactly what you want, but in my opinion it is not remotely easy. ...

Windows should be detected while you manually install Ubuntu 14.10 and added to GRUB. If it is not added initially, boot into Ubuntu, install Boot Repair and run that. That should add Windows 10 to your GRUB. Source: I have run a Windows 10, Ubuntu 14.10, elementary OS, Fedora quad boot

You need to free up space or your device - you can use a bog standard android file manager for this (you may need to delete some large apps as well) - though it can help to have a program such as a DiskUsage which shows which files are taking up space: For installation, What hardware does Ubuntu Touch support? should be helpful

I found a long and dangerous (for my tab) way to install it although it is not dual booting. I installed Ubuntu 14.04 onto an ssd card and swapped out the prebuilt ssd card for the one with Ubuntu. For some reason the touch screen quit working with Ubuntu though.

I had a somehow similar problem. After installing ubuntu side-by-side with windows 8, it always booted straight into windows. My solution: Even though I installed ubuntu with bios-boot-setting UEFI, I can now boot ubuntu by setting bios-boot-setting back to legacy. For booting windows I set it to UEFI. Of course, entering the bios each time I want to boot ...

99% the answer would be "yes" - but not 100% sure. It's impossible to tell about ALL Asus computers, but really I've never seen a modern laptop being unable to run Ubuntu and Windows in dual boot. (Maybe I'm just lucky ;)) I recommend you to try Xubuntu or Lubuntu, they should run faster than Ubuntu.

Since both OSes had issues, it is not a software issue. Diagnostics cannot check all the possible functions of the hardware. You may be lucky, perhaps it's simply a temperature issue and it's freezing on overheating. What kinds of temperatures are you seeing on CPU and GPU? Does your bios have a system event log? Does it show any failure warnings? If you ...

Changing the partition size does not automatically change the filesystem size, so try just putting the partitions back to the way they were, and see if Windows not works. If so, resize next time from within Windows, then run chkdisk a few times before doing anything else. Did you look on the bottom of the machine for a label with a product key (if you ...

Assuming that your Linux file system is on (hd0,1) If you want to list files in the partition try grub> ls (hd0,1)/ (It will only with the filesystem containing Linux) grub> set root=(hd0,1) Also check the name for your vmlinuz and initrd file. grub> linux /boot/vmlinuz root=/dev/sda1 (sda1 will change according to your Linux filesystem) ...

I figured it out. Windows has a unique bootloader that unetbootin - designed for linux - doesn't correctly see and use. Used a friends computer and made a flash drive with rufus with no problem whatsoever. Thanks for being completely useless for three months.

The EFI partition just contains a FAT filesystem, so you can mount it, create a directory /EFI/ubuntu and copy /usr/lib/grub/x86_64-efi-signed/grubx64.efi.signed into /EFI/ubuntu/grubx64.efi and /usr/lib/shim/shim.efi.signed into /EFI/ubuntu/shimx64.efi. Now if your nvram boot entry was deleted,m you will need to use efibootmgr to create another. One real ...

Also might need to disable the TPM as well as the Secure Boot. We found Surface Pro 3 has very long boot time with TPM (probably checking hardware changes possibly resulting from Ubuntu operations?). Also, we found that after some time the Grub menu disappeared after working for many boot cycles. Perhaps the TPM is the culprit changing the boot procedure ...

We got it work on Surface Pro 3 by doing the USB Ubuntu 14.04 install following the posts above. However, we needed to set the bootloader to be on /dev/sda2 (second partition with label EFI Partition) not the default one /dev/sda ATA SAMSUNG. This solved the issue for us. We also found you can access the Ubuntu install by using the Update and Recover ...

For Windows 8.1 on Surface Pro 3, we found it was very important to choose the EFI partition (for us also /dev/sda2 (not default /dev/sda). If not, the GRUB menu did not appear. Another helpful hint for Surface Pro 3. When is loads directly to Windows, to get to Ubuntu you can also go to Update and Recovery screen and then select Restart Now. This ...

The partitions look alright. I would put the boot loader on sdb though, because it's faster and that's where the operating systems reside anyway.

I can barely follow your full question, so I'll just answer the "Input/Output error during install through USB", assuming it's a USB input/output error. If you could post the exact error messages (should be some in /var/log/syslog or dmesg, maybe even with lsblk to see which drive is which) that would help show if it's USB errors or HD errors. I get ...

To install them I create a / and a /home partition for each distribution, but the EFI boot partition which is created by W8 at the begining of the disk is unique. Looks good to me, I would have done the same. Is there any problem with installing various linux bootloaders in the same boot partition (maybe because kernels get mixed or something)? ...


0

Yes it is: For Windows with Ubuntu dual boot: Assuming that you had installed Ubuntu after installing Windows, such that Ubuntu is on the upper end of this disk, you would therefore want to reduce the size of your Ubuntu partition to provide free unused space for the overprovisioning. GPartEd free tool that comes with Ubuntu is ideal for this. If you need ...

It seems like you're just copying the ISO file to a DVD or USB. As you're currently running XP, just install ImgBurn, open the ISO file in there and then burn it and boot with that. Alternatively, if you want to use the USB use UNetbootin (it has a Windows version) and use that to put the ISO file on there. Why? An ISO file is an image that contains the ...

The system is unbootable because the Mac bootloader expects the EFI partition to be formatted as HFS+, the typical Mac filesystem, while the Ubuntu installer actually formats it as VFAT. Refer to my earlier answer for detailed steps to install Ubuntu properly on a Mac.

If you are already in the Ubuntu, you can change the boot order by using Grub Customizer. Just install it by typing this command in Ubuntu terminal: sudo apt-get install grub-customizer This Grub Customizer has a Graphical User Interface. Once you open the program in Ubuntu, there would be some option to set the computer boot order. ...

This is not really an Ubuntu question, but an Elementary OS question, but Elementary comes with its own version of grub, so I would: Take a full system backup using CloneZilla Take another backup with your current backup Boot Elementary OS, delete the Ubuntu system partition Recreate a new partition with the same settings as the Ubuntu partition be sorry ...

/dev/sda1 is your root partition, which indeed can not be unmounted while Ubuntu is running off of it, because this is where the operating system is. What I usually do in such cases is to boot from a live CD (my favorite is systemrescuecd) and then resize the partition while it is not active.

this took me a while but it payed off it was a mix of my own digging and answers above first make sure your /etc/default/grub and /usr/grub/default/grub are the same. then run gksu gedit /etc/grub.d/30_os-prober near the top are the two lines we want but to find them search for styke and change that line to hidden then search for a timeout line it should be ...

I'd imagine you will need a windows disc, start windows installer via the boot menu, and then run boot repair. I don't know if something like Ultimate boot cd or system rescue cd will work as I've never had a need to use them. BTW, its called dual boot not side-by-side. Apparently, it looks like you didn't do it correctly.
