Hello, As instructed, I disconnected the other drives, leaving the main harddrive and the DVD-RW drive. This did not had any effect: grub 2.02 showed the same error: error: disk 'hd0,msdos5' not found. booting from a CD and restoring grub 2.00 (sudo dkpg -i grub* in the directory where I keep a copy of the grub debs) put the system back in bootable state. I have attached the device.map file found in /boot/grub. The identification of hd0 is correct. Also in grub.cfg, one can read: if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos5 --hint-efi=hd0,msdos5 --hint-baremetal=ahci0,msdos5 --hint='hd0,msdos5' 94ecf542-619c-4fe7-bfed-672fa7bb2739 else search --no-floppy --fs-uuid --set=root 94ecf542-619c-4fe7-bfed-672fa7bb2739 fi The uuid is indeed the one of hd0,msdos5.
msdos5 (or sda5) is the first partition within the extended partition sda3. sda1 & sda2 are primary partitions for Windows. sda6 is the swap, and sda7 is mounted as /home. Could this be troubling Grub? The configuration of the hardware hasn't changed since I assembled it, and installed the Windows and Xubuntu. I am still ready to help and test whatever solution you may come up with.
