EricJD Posted January 24, 2006 Share Posted January 24, 2006 Hi, I finally got OSx86 installed and working perfectly on my Dell Optiplex GX270 But now when I use fdisk to change the active partition back to my Windows XP partition, I get an "Error loading operating system" message on bootup... So I switch back to my OSx86 partition and it works fine... Then I go back to my XP partition and it still gives me the message. Can someone help me? Will I need to re-install Windows XP? (if I really need to, that's not a big deal, I just had to re-install it a few days ago anyway...)

a8ne Posted January 25, 2006 Share Posted January 25, 2006 XP disk >> press "R" for recovery >> choose your windows installation >> enter password >> bootcfg /rebuild It's a lot easier to use grub, i.e., install your favorite linux distro, add osx86 and XP to /boot/grub/menu.lst Link to comment https://www.insanelymac.com/forum/topic/7634-active-partition-change-problem/#findComment-47992 Share on other sites More sharing options...
wingzero Posted January 25, 2006 Share Posted January 25, 2006 If you end up reinstalling for some reason install this way: 1 Boot to OSX install disc 2 Make 2 partitions, 1 DOS and one Mac (in that order) 3 Reboot to Windows install disc (make sure you are installing on the partition created for DOS. 4 Make sure windows boots up fine, you should not be able to see the MAC partition in My Computer 5 Boot to OSX and install new installation on MAC partition. 6 Reboot, you should now see a boot menu similar to : hd0(1) Windows NTFS hd0(2) Mac OSX Hope that helps!
