Hi all Working on multibooting BartPE on a 4GB usb stick. Layout - (2) 500MB FAT16 partitions - both primary PEtoUSB.exe to create minint and Programs folders onto 1st partition. Installed Grub4Dos. Edit menu.lst - Boots perfectly. Moved all files/folders to 2nd partition except menu.lst and grldr. Edited menu.lst: title BartPE hide (hd0,0) unhide (hd0,1) rootnoverify (hd0,1)/minint/setupldr.bin chainloader +1 makeactive boot NTDETECT failure. Move all files back to first partition, change menu.lst back to (hd0,0) and it boots fine again. What am I missing here? Thanks!
