Wed 29 Feb 2012 06:23:04 PM UTC, comment #6: Some BIOS are limited to some particular disk size, usually 128GiB. You can check this by booting into a working GRUB (e.g. on external storage and issuing ls -l and compare reported disk size with real one) |

Wed 29 Feb 2012 06:20:11 PM UTC, comment #5: I would also point out, that this particular machine has used Acronis TrueImage v8.0 build 937 since it was released - and Acronis has no issues with the BIOS. As I understand it, Acronis is essentially Linux code - rewrites the MBR when creating and restoring partition images from within Windows. Gparted from withing PartedMagic also has no issues resizing, formatting, setting flags or designating the boot partition - be it linux, swap or ntfs.

Corresponding source code
The reporter failed to provide the requested info (output of "ls -l" and whether grub-fstest and grub-probe work), instead supplying loads of irrelevant unrequested info. Since there is a plausible explanation (BIOS limit) and workaround (--disk-module), closing the bug report.
