I have a 2001 Dell PC with Windows XP and Windows 98 SE. When I installed Windows 98 and re-installed XP about a year ago, I created a 6 GB (C:) partition for Win98 and the rest of the disk (D:) for WinXP. I edited boot.ini to give a nice menu upon boot, and all was well. Eventually, 6 GB became to small for me, and I needed to expand the partition. I booted up a live Linux USB pendrive a few days ago and used Gparted to expand the Win98 partition to 60 GB and shrink the WinXP partition. Apparently, Gparted touched something in the MBR that it shouldn't have, and I got the "Invalid system disk. Replace the disk and press any key" message when trying to boot Win98. XP had no problems booting after the partition resize. I booted up a Win98 startup floppy disk and ran sys c: which then allowed Win98 to boot up correctly, but I no longer get the boot menu to select XP. I can make XP boot again by booting up the recovery console from the CD and running fixboot, but then this makes Win98 give the "Invalid system disk" message when trying to boot it. My problem is that I can get either XP or Win98 to boot, but not both. How do I restore the proper boot sectors to allow me to dual-boot the OSes?
