I'm new to Ubuntu and Linux. And I'm running into a Grub rescue no such device error.
I have an older desktop with two hard drives: 60GB and 500GB (resp.
sdb). I think they're PATA. I can't set
/dev/sdb in Boot Sequence (probably due to the fact that an older BIOS can't boot from a slave drive).
I've just installed Ubuntu on
/dev/sdb2, while I selected
/dev/sda as 'Device for boot loader installation' and the swap on
/dev/sda6/ (See my related previous question on this site). I wanted to make a dual-boot for Windows XP (SP3) and Ubuntu 14.04. Windows XP is running on
/dev/sda2 on a 40GB partition.
So I have put
/dev/sdb2 and I wanted Grub to be on
/dev/sda because I could not set the Boot Sequence in Bios to boot from
/dev/sdb which would be necessary otherwise for booting into Grub.
When I was all done with installing Ubunutu from Live DVD, it asked me to 'Reboot Now', so I did. Then an Ubuntu screen appeared, but like only half the size of my 15" monitor in the left upper corner. Then nothing... for over 10 minutes. No reaction to keyboard. So I unplugged the power.
Now I booted again, and pretty soon a grub rescue error appeared:
Error: no such device: 2785cb02-5d56-4a3a-8e69-f6f950b92f0e
Entering rescue mode...
My question is: How do I get from this to a smooth dual-boot system?
I used Boot-Repair-Disk-32bit already, and ran the 'Recommanded Repair'. But I still encountered the same grub rescue error afterwards. Also running it with 'Advanced Options' and checking 'Place GRUB in all disks', I still get the error.
I did discover that the device mentioned in the error ('no such device') is in fact
/dev/sdb2, being the ubuntu partition (or
/root partition). This partition showed up in 'FileManager > PCManFM' when running it from the Boot-Repair-Disk. And it showed the same number as the error has.
I remember while installing Ubuntu, and while deleting and making the
/dev/sdb2 partition -with mount point
/- switching this to 'primary', while the default setting was 'logical'. Could this be of influence?
The Boot-Repair-Disk made a few BootInfo Summeries. I have these url's available (not allowed so may links yet).
Please help me finish this installation. Thnx.
