Been playing around with WinsetupfromUSB today (last few hours..)
Somethings to note.
Windows 7 easy. Any stick should work USB 2 or 3. (Although I did not try it in the USB3 port yet.. WOW would that be fast
)
Windows XP, MUST use a USB2 stick. Even in USB2 ports usb3 throws errors (0x69 BSOD). Use NTFS, and XP installs in about 5 minutes on a 120X drive.
Another thing is that tinyXP rev9 will not load I tried options 5 and 7 for making the ISOs before extracting them and mounting to USB. Both throw KBDUS.DLL errors. (US keyboard layout) Tried replacing them, makecab/expand/modifyPE on the files, nothing worked.
Finally took some stupid XP SP3 I had laying around and fired it up on USB2 first try. Going to rebuild as it was one of those terrible eXperience builds.
I will work on figuring out how to integrate drivers into FLP next, and should have a nice USB multiboot stick soon! (Going to need a larger USB2 drive though... 8GB wont hold benching OSes and Install OSes :O )
