I tried booting off with a FreeDOS USB , with grub4dos added. It was prepared with HP tool. and grub4dos started via autoexec.bat. I use it to chainload to a USB, prepared with WinSetupFromUSB
When the USB boots, I do
map (hd0) (hd2) map (hd2) (hd0) map --hook uuid (to check if I mapped everything correct) find --set-root /grldr boot
At this point green.yellow grub screen of WinSetupFromUSB will welcome me
Here things can go two ways
1)If I try to boot and DOS-USB is still plugged, the setup will report that TXTSETUP.SIF(as far as I remember) was not found
2) If I plug out the DOS-USB and only the WinSetupFromUSB is plugged, everything will work as normal.
Just anted to let you all know
