[Boot-Repair] Graphical tool to repair the PC boot in one click

Do you get grub menu? If so remove quiet splash and see if we can get more detail on error.
At grub menu use e for edit, scroll to linux line and edit out quiet splash and boot.
It scrolls by quickly and last lines often are not issue, but several lines above that.

Does recovery mode also give same error?

Hi oldfred,

Yes - I do get the grub menu, I tried your suggestion - I don't see any obvious errors but here's a screenshot anyways:

I also tried disabling swap, but that hasn't made a difference either.

You show a grub install to the MBR, but have Ubuntu in UEFI boot mode. You need to be sure you always boot in UEFI boot mode. Do not know about Easy2Boot. Is that UEFI? If not that may be an issue as it is better to always be the same. Or you did not switch back to BIOS boot mode to boot flash drive. I do not see flash drive in BootInfo report.

Thanks Old Fred. Easy2Boot is a a grub4dos multiboot USB drive that allows me to boot to different distros including windows ;it seems to be working now.
You say boot repair shows a grub install to MBR, does that need to be removed?

@darknomel
Still says corruption. And you did run e2fsck which did not look like it found any corruption.
Usually if swap has issues you can just skip it and it still boots.
Did you run the efsck on all ext4 partitions?

@superfreak
You do not need to remove grub from MBR, as it is not really used. But do not boot with BIOS mode or it will try to start grub and give a grub> command line.

grub4dos is the old version of grub that works in NTFS partitions. But grub2 also works in NTFS partitions. I prefer to use grub2 for multi-booting but I think I suggested that before.

hi, just tried this tool with partial success
here is my log link http://paste.ubuntu.com/6881607/

some history:
i had windows 7 and ubuntu 12.04 installed on the same HD all working fine
when i installed 13.04 over 12.04 windows boot was broken
seems like the MBR could have been written over

now grub shows up with various ubuntu boot options, but no windows boot option

any help would be much appreciated

@steeve
You have a main Windows install in sda4. But Windows has a (hidden in Windows) 100MB NTFS boot partition that usually is the first partition. Boot flag is still on that partition which would say that was the Windows boot partition.

But you first partition which is 100MB has something called BootIt? Never heard of that and it is not Ubuntu nor Boot-Repair related.

With Windows you do not have to have a separate boot partition. You need to move your boot flag to sda4 and yse a Windows repair disk to fix it. You need to get bootmgr & BCD which are now missing into your Windows partition.

thanks oldfred - i'll move the boot flag and try to repair the windows boot
BootIt is a boot manager that I have used in the past
thanks for your patient service in this thread!

Hi all,

I think I need some help with boot repair...
I've installed the latest Ubuntu release 13.10 (from a live USB) in dual boot with a preinstalled windows 8 on a sony vaio Pro 13 laptop.
Once ubuntu install completed, I rebooted, and it directly went on windows (I had no choice).
So I installed and executed boot repair from my ubuntu live usb (clicking on "Recommended repair"), answering "Yes" to the last question "backup and rename windows EFI files" and rebooted again, nothing had changed.
Here is the log :
http://paste.ubuntu.com/6875324/

I tried again, as suggested, answering "No" to the ""backup and rename windows EFI files" and.... I can't boot anymore (no windows, no ubuntu).
Here is the second log :
http://paste.ubuntu.com/6875636/

The last log told me "Please do not forget to make your BIOS boot on sda3/EFI/ubuntu/shimx64.efi file!", but I can't find any option like that in my BIOS/UEFI or whatever.

Can someone help ?

Thanks !

Clement

Hello,


My server (KVM virtual machine with Ubuntu 12.04.3 Server) doesn't boot anymore since the hosting company had to do an unschedule maintenance on the hardware…




I've tried to boot on the Ubuntu Desktop live CD and run the following command

fdisk -l

*** we figure out the root partition is on vdb1 ***

fsck /dev/vdb1

*** answer yes to all questions ***

mkdir /mnt/backup
mount /dev/vdb1 /mnt/backup
ls /mnt/backup
> grub-mkconfig_lib i386-pc lost+found update-grub_lib

Here I only see grub files, not our files ;-(


Then I've tried to install and run boot-repair from the LiveCD in Recommended repair. I don't know which partition he tried to repair, but it finished successfully. However the partition still hangs at GRUB.


Here is the boot info script: http://paste.ubuntu.com/6885670/


I wonder what to do next, shall I use the Advanced mode ?


Thanks a lot for your advice

Sylvain

Your entry is usually just ubuntu, but details show shim:

Boot0000* Windows Boot Manager HD(3,363800,82000,dcf14e60-ee5f-40be-a3e1-5227aa427b27)File(EFIMicrosoftBootbootmgfw.efi)WIN DOWS.........x...B.C.D.O.B.J.E.C.T.=.{.9.d.e.a.8.6 .2.c.-.5.c.d.d.-.4.e.7.0.-.a.c.c.1.-.f.3.2.b.3.4.4.d.4.7.9.5.}....................

Some vendors modify UEFI to only boot Windows. So the rename is to change the Windows efi file to really be grub or shim and then it will boot to grub menu. Then you only can boot the renamed Windows file from grub. But if you can boot the ubuntu entry you should undo the renam. And with rename both ubuntu entry (if it works) and Windows entry should take you to grub menu.
If you can boot ubuntu entry.
To undo & to rename files to their original names, you just need to tick the "Restore EFI backups" option of Boot-Repair.


@sylvain-tissot

It does not look like Boot-Repair works with KVM virtual installs. And I do not know about them. And I really do not know about servers. May be best to post in Server sub-forum.
Not sure how you mount & boot kvm install. This is for typical installs:

Thank you oldfred !
I've just restored the EFI backups, and i'm back to the initial problem :
both windows and ubuntu installed, but I get no grub menu, and windows boots without asking anything (I never see ubuntu).
