I'm trying to set up dual boot with Windows 7 and XP according to this tutorial:http://www.sevenforums.com/tutorials/8057-dual-boot-installation-windows-7-xp.html.. EasyBCD version is 1.7.2. Windows 7 was factory installed and working fine, then I installed Windows XP in a new partition. Current hard drive layout is R:->Win 7 recovery partition, F:->system partition, contains windows 7 install and boot files (BOOT folder repaired w/EasyBCD, BOOTMGR, NTLDR, and BOOT.INI), G:->Windows XP install, and D:->Data volume. I'm trying to first add Windows XP entry according to tutorial. The "Drive" parameter is set to D: and can't be changed. If I click Add Entry anyway, I get an "unhandled exception" error, "Index and count must refer to a location within the string". I get the error when trying to add Windows 7 (Vista/Longhorn) also, using drive F:.
