10 GB NTLDR
Have XP on old drive, installed Win 7 OEM on new blank drive, it never saw the xp install or offered up any dual boot options, installed EasyBCD Beta 2 build 76 on XP boot, manually pointed it to the BCD on the 200 MB system partition on the Win 7 drive, added entry for the XP boot and got the huge NTLDR file on the XP drive. Gonna go experiment.
Addendum:
Note that I am picking which drive to boot to with bios boot menu. I pick an IDE drive for the xp boot, one of two sata drives for the win 7 boot. The win 7 boot is the one I'm trying to multi-boot with. I am booting into XP to run EasyBCD to try the setup. Had tried doing it from Win 7 boot earlier 1.7.2 ? version. Maybe I'll try that again with beta version.
Replaced ntldr and ntdetect.com with backups - back to original state. Recreated XP boot entry with EasyBCD, it pointed to drive C: and changing not allowed while creating it. Went to view entry and is showed pointing to \ntldr on F:, the 100 MB system partition for Win 7. Went back to edit tab which now showed F: and would let me change it to c: and it did store correctly that time.
Upon boot to boot loader XP, hung for a little like it was trying, then it completely rebooted on its own. Copied ntldr and ntdetect.com from your Profiles directory to the XP drive, tried again, this time it said invalid boot.ini file, tried ntdetect from c:\windows and failed.
Said heck with it, enough for one night. Also, when saving config to a bcd file with your backup, it says saved in status bar but no file is ever created.
Don't need the dual boot this bad. It's not being at all easy. Some other time...
Addendum:
Very sweet. Installed the beta in the Win 7 boot and the world is right again. Recreated the XP boot entry and it automatically installed the ntldr and ntdetect.com properly. Saves backup bcd files properly now too. Apparently it's not completely compatible with my XP boot.
Works very well now. Can have bios boot to the Win 7 drive, will boot to whichever is the default and I can change which is the default with EasyBCD in either boot. Good deal.
