Comment 11 for bug 384633

I found the original grub.cfg file from a USB hard disk install. It does use UUIDs on the linux line, just the hdx references are wrong. This probably would have booted Maverick successfully, but maybe not Windows, which does the search with UUID, but used the bad hd1 for the drvemap. The fstab file also used UUID for the root and swap, just having the "leftover" comments about the devices being on /dev/sdcx at install (comments which no longer appear in the grub.cfg file).
grub.cfg from a maverick created 2G USB installer to a USB hard disk target -- only hx? references are wrong but may still boot linux.but probably not Windows:
