GRUB setup/repair

Not strictly an installation issue, but I have the following problem:

I installed Arch about a month ago as my only OS and about a week ago I installed Kali, so my partition scheme was something like:
sda1: Arch (boot flag)
sda3: extended
sda5: Kali
sda6: swap
Then today I split a 4 GiB chunk off of sda1 to form sda2 and installed Windows XP from an USB, of course I forgot it would overwrite GRUB.

I resintalled GRUB to sda, but I can't figure out how to configure it properly.

I tried pretty much the same thing from an Arch and a Fedora DVD: ran grub(2)-configure, checked output to see if all OSes are recognized (on Arch I installed os-prober first), ran it again with `-o /<arch mount>/boot/grub/grub.cfg`.
On Arch I also otried it from an arch-chroot to the mounted Arch partition, as far as I could tell the result was the same.

After GRUB boots I get an error message about a missing partition and the UUID that it has.
I checked `blkid` in Arch and it turns out the UUID is loop1's, similar thing happened on Fedora. My understanding is that os-prober is detecting the currently booted live system in both cases.

Is there a way to disable this? More specifically, is there a way to disable search of certain paths?
I'm aware that os-prober is a shell script, so I could "just edit it", but I checked it and I can't really understand what's going on in it, only some basics.

Re: GRUB setup/repair

Could you post output of bootinfoscript?

Sorry, I was impatient and just downloaded a boot-repair disk and used that.
If the bootinfoscript output is still relevant, I'll upload it.

However, I'm curious about what information os-prober uses exactly and what paths it tries.

Re: GRUB setup/repair

Hi everybody,

I was running archlinux on an external usb and then tried to intall and run Unity desktop manager instead on the xfce desktop . I failed and Arch loads Unity before freezing.......
I want to know if there's a way, script or command to revert back to xfce in terminal through Fedora ( instead of booting from an Archlive usb or cd )

Thank you in advance fro your precious time

Regards

Caron

carongangoo,

This is a marginally old thread that is tangentially relevant to your issue.  I am going to go ahead and close it and invite you to start a new thread of your own.  If you really feel this thread is relevant, you can always link back to it.

Thanks
