Does anyone know what it takes to cause this bug? Is it related to upgrading from FC1? Only when you install FC2 on the same HD as Windows? Only if you use the installer to change the partitioning? Some combination of these?
See my previous post for the long exlanation. The short explanation is that the partition table is written with the wrong geometry and wrong partition starts in cyl,head,sector (but correct in block numbers) in some cases.
This would happen if ALL of the following are true: --the install writes the partition table --the partition table is written by a utility or component which obtains the geometry from /proc --the install is being run under a 2.6 kernel that puts the IDE/ATA geometry instead of the BIOS geometry in the "standard place" in /proc. (Remember that the install runs under a Linux kernel; e.g. the Fedora 2 ISO CD/Rom runs the install under a 2.6 kernel. And the install kernel of Fedora 2 IS one of them that puts the "wrong" geometry in /proc)
Apparently on some systems Windows XP will boot with bad geometry in the partition table, but won't on others. Linux doesn't care about the geometry in the partition table.
