Re: Call for testing with dual-boot scenarios (or more accurately, call for information)

Could people who have experienced difficulty with dual-booting between
their FC2 test2 installs and a Windows install of some sort get as much
as possible of the following information for me?


If you could add the information to bug 116653, that'll be the most
helpful for tracking purposes, although mailing it here won't hurt as
well.

1) The geometry as reported by parted (if you can get from an old FC1
install and an FC2, that would really rule)
2) modprobe edd and then get the values from all of the files in
/sys/firmware/edd/int13_dev80
3) The output of 'geometry (hd0)' from a grub prompt in a running 2.6
kernel
4) The output of 'geometry (hd0)' from a grub prompt when booting from
the BIOS

Thanks,

Jeremy


Here is some info from my dual boot system. (it really is a quad boot system) My box has two drives that are both set up to dual boot. I have winXP and RH9 on hda and wixXP and FC 1.91 on hdc (I change the bios boot order to switch drives for booting)
The FC 1.91 install was done by installing FC 1 and yum updating the rest to current /develpment. This info may not be as helpful as if I had installed FC 2 test 2 but if may be useful for reference since I can boot into any of the 4 installed systems. I have grub in both MBR but only boot into the 2 systems on the drive I am booting from.


hope this helps,
Richard Hally

here is the output from parted print:

Warning: Unable to align partition properly. This probably means that another
partitioning tool generated an incorrect partition table, because it didn't havethe correct BIOS geometry. It is safe to ignore,but ignoring may cause
