GRUB is designed to take over control of the initial stages of the boot process. This works fine on a single-boot system (Ubuntu only, say) or when dual-booting one GRUB-based OS (like Ubuntu) with Windows; but when you install two GRUB-based OSes (like Ubuntu and Mint), the two GRUBs will fight for control of the boot process. Experienced multi-booters ...

Assuming that your Ubuntu installation is intact (not a safe assumption), you should be able to get up and running again as follows: Download the USB flash drive or CD-R version of my rEFInd boot manager. Prepare a medium from the downloaded files. If necessary, disable Secure Boot. (There are ways to do this with Secure Boot active, but they require ...

Your wifi might be disable for several reasons. I suggest you look into the logs (journalctl -b -0 if you use a recent version of Ubuntu). This might be a problem with your network-manager configuration (assuming you use network-manager to access Internet, which is the default in Ubuntu), which can be found in the folder /var/lib/NetworkManager/. EDIT: ...

Using the kernel that comes from LTS (3.19). Noticed that having persistent on the command line and NO caspar-rw FILE will stop the boot process in busybox. Adding the casper-rw file removes that problem. My work-around for now is use a small casper-rw file AND and home-rw partition which cover the remainder of the thumb drive.

It's possible Grub was installed to the flash drive. I had this happen once several years ago and the computer would not boot unless the flash drive was attached, even though I had another system installed on the hard drive.

If you have multiple installs using grub2, only one of them can be in MBR and controls booting. That usually is the last install. And you may have issues if you installed both originally to MBR of same drive. Grub remembers where it installed and a major update of grub will reinstall it. Or either or both installs may be updating grub. I like to document how ...

You could have still startd the programs with their full path, for example /usr/bin/vim. Since most programs didn't work for you, you could have checked packages.ubuntu.com for their paths: http://packages.ubuntu.com/trusty/amd64/nano/filelist Alternatively you could have booted into recovery mode and opened a shell there I guess.

I just managed to solve my problem, this is how. I did not have a LiveUSB Linux so I rebooted with my Windows partition. I then installed ext2fsd on Windows and was able to read my partition with Ubuntu. I corrected the erroneous $PATH$ (I had made an mistake in the file \etc\environment) and rebooted. Note that modifying a linux system file from windows is ...

Maybe my question is a little bit stupid but is the phone charged ? Because I noticed on my phone that battery can go from 50% to 1% really fast. Try to do it when your phone is connected to supply power. If it's not come from battery try to remove SD card and SIM.

I have an hp pavillion g6 A8 quad with windows 10. In the uefi (bios) mode in order to get Ubuntu to load or to even see it I enabled legacy mode. To boot windows 10 you have to disable legacy mode.

If you have multiple disk you may have to change in your bios the default one to boot in. The disk you have selected has only BCD (windows boot chain loader) so it uses that. Btw linux is not installed on windows bootchainloader, if you want to you can try to use EasyBCD (http://www.majorgeeks.com/files/details/easybcd.html) to edit this. Otherwise you may ...

Maybe this is a hardware (AMD graphics) related issue. Boot from CD - choose "Try ubuntu without installing". After the desktop appears start installation from here.

Follow these instructions. They may help you. In BIOS, go to UEFI/BIOS boot mode and select Legacy. Change your boot order to have First boot device as USB. Save changes in BIOS and exit. If still your new os doesn't boot, It means that your usb is unbootable. To make a bootable usb for any Linux distro on Linux (other working computer) use UNetbootin. ...

I went through this recently. I ran a Lenovo laptop with Windows 10. I set it up to dual boot Windows 10 with Ubuntu 15.04. (It seems that it will be more difficult if you try to install an earlier distribution, see here for a tutorial.) If you're using Windows, you can hold 'Shift' when you click restart on the start menu to access the recovery options. ...

You probably need to disable Secure Boot. On most new machine, the UEFI BIOS will not boot from OS's other than what it came with or similar.

If you take a look through /etc/init folder, the command responsible for bringing up TTY is getty. For each TTY there is a *.conf file in /etc/init , so if you want colorized prompt on every TTY, you will have to edit every single one of those files. Now, the file responsible for the contents of that appear on the screen before logging in is /etc/issue, ...

I really do appreciate your answer, but it did not work in my case. But, I did try another separate usb. Used Unetbootin to make Ubuntu 14.04.3LTS Live USB. Booted with live USB.

Had the same problem and tried this. When computer comes on, go to the option which usually works for me it was the first on the grub menu(Ubuntu 14.04) and press 'e'.

I did something similar, but without LVM and encryption. You may perhaps still find something from the instructions here, especially if your system boots via EFI.

This is the longest post I've ever made on a StackExchange site, but this process requires a lot of explanation and attention to detail. It's also somewhat specific to the hardware in question, which requires more explanation.

This means that upower is hanging. There are multiple reports about but apparently no solution yet. It seems this is related to failure in reporting the battery status. This related question has more information about it. It suggests a workaround which will probably not work in your situation.

Few days ago I tried to install Windows 10 using USB stick, but couldn't because Ubuntu didn't boot it. So, that's a misconception here. Ubuntu won't boot from your USB stick. That has to happen before you boot Ubuntu or any other operating system. First off, not all computers can boot from USB, they need to be sufficiently new to support this (the ...

Find your current running kernel with: uname -r Then delete any vmlinuz/initrd kernel & image files from boot provided they are not the running kernel. I suggest you create a copy of the running kernel somewhere first just in case you make a mistake. You can remove old kernels several ways. Just deleting them (not recommended). Use a tool: How do ...

Okay, finally got it to work this morning. This time I installed both to the SSD again, making extra sure to direct Ubuntu to the Windows EFI partition during installation.

I did this recently with a SSD in a USB 3.0 housing and it worked very well on a USB 3.0 port of a Lenovo S1 Yoga. I tested it with a USB 3.0 64GB key and it was not that smooth. Running it from USB 2.0 is too slow to work with. I also tested it with Win 8.1 and Office - no problem like an internal HDD. One thing: I could not install an anti virus scanner ...

I might need some more info, but here is what I know on how to fix this: During the boot logo, press ctrl + alt + f1 and login with your user name (UNIX user name, not the greeter user name) and run sudo apt-get purge <insert driver package name here>. This should clear the drivers and fix the computer.

It is unlikely that you system is usable after removing the /lib directory, since this contains the runtime linker (e.g., /lib/x86_64-linux-gnu/ld-2.21.so). Without this file you will not be able to run any dynamically linked binaries (which, in general, means everything). Any attempt to restore these directories is probably going to be complex and error ...

Try to check to boot from legacy mode and select boot from USB. Upon this selection your laptop should restart and quickly plugin your bootable USB. I have also encountered the same issue before. Playing around on bios startup fixed it. Hope this works.

From LFS guide: LFS is usually installed on a dedicated partition.
