I have a windows 8.1 preview (upgraded from 8) on my system. I have one HDD or 1 TB, with one drive 228 GB for ubuntu.
I downloaded 13.04 (64 bit) from ubuntu's site. used pendrivelinux to create a bootable usb. restarted the computer, and booted from USB (from UEFI menu). selected try ubuntu without install installed ubuntu made 4 partitions:- boot, root, home and swap. all went well and the prompt came asking me to restart the system. Once i clicked the restart button, windows loaded without asking for any OS choice.
so i restarted the system again went into boot menu, which showed, ubuntu also. Selected it and pressed enter, again windows loaded.
So i googled a bit and installed easybcd, this is what it said.
There are a total of 3 entries listed in the bootloader.
Default: Windows 8.1 Preview
Timeout: 30 seconds
EasyBCD Boot Device: C:\
Entry #1
Name: Ubuntu
BCD ID: {63712191-130f-11e3-bef6-84a6c82584a5}
Device: \Device\HarddiskVolume1
Bootloader Path: \EFI\ubuntu\grubx64.efi
Entry #2
Name: EFI USB Device
BCD ID: {0bd5b854-4556-11e2-8925-d4bed9614efa}
Device: Unknown
Bootloader Path:
Entry #3
Name: Windows 8.1 Preview
BCD ID: {current}
Drive: C:\
Bootloader Path: \WINDOWS\system32\winload.efi
I tried adding a new entry also as told on many sites, but all in vain.
I checked to see if ubuntu is actually installed or not. So when i tried to reinstall ubuntu, it said that it is already installed.
So what can I do now?
Based upon the suggestion, i installed boot repair. ran boot repair and selected recommended option in boot repair. system said that i need to turn off secure boot. and then completed saying that i can restart. On restart nothing changed with or without the secure boot disabled. That is no boot menu. straight away going to windows.
So i logged in again via USB installed boot repair again. ran boot repair in advanced mode, but wit default options checked. system asks me to run a few commands (3) followed by another command. then says to restart.
On restart this time the USB loads itself, as if there is no windows or ubuntu installed. I checked the boot menu and there is no windows or ubuntu.
Current boot info summary is: http://paste.ubuntu.com/6059160/
Currently I have secure boot off, i guess i t is required to be disabled for dual boot.
in advanced boot, the default option selected was sd6 for /boot partition and sd1 for boot/efi partition
My boot repair screen is different from your's.
Then I went ahead and reinstalled ubuntu (deleted the previous install) Ubuntu is working fine now.
Now i need to find a way to bring back windows to life. Please suggest how to do that.
