I looked at my system and I have the same problem :-)
The fix was :
- sfdisk -d /dev/hdc | sfdisk -H 255 -S 63 --force /dev/hdc
WARNING ! DO NOT BLINDLY COPY THE ABOVE !
BACKUP the partition table to somewhere where you can access
it if you break the disk layout ! Like on a floppy or network drive.
"sfdisk -d > part_table_backup" is a good backup IMO.
- read the sfdisk man
- set BIOS disk mode to LBA and boot grub. Do not select an OS but go to
the command line by pressing 'c', then enter : geometry (hd0)
- note the output. If the head and sector numbers are 255 and 63, then
proceed and use the same fix as I did. Otherwiese use your own numbers.
- then you can set the BIOS disk option back to AUTO.
Is this bug reported ?
