HI:

This is just a heads-up about an issue you may not know off......

After prepping a Windows 7 external USB HD everythings works GREAT.....

..... UNTIL the drive is accidentally plugged into a PC booted from Windows 8.1.

Apparently 8.1 modifies something on the HD because the next time I boot from the W7 USB Ext drive, the boot fails (after showing the W7 startup logo) by dropping back to the BIOS display screen.

It boots again and this time gives me the option to run a bootup repair or continue starting windows normally. I continue starting windows normally and everything if fine.

Everything keeps working fine unless I once again plug the ext drive into a W8.1 booted computer. Then it does the same routine again.

Windows 8 certainly does something to the ext drive to mess it up for W7 booting.

Boowho??

I have a spare SSD (64gig) that I am trying to use WinToUSB on. I have tried creating a 110mb partition formated either NTFS or Fat32 and the rest of the drive as the boot partition formated at ntfs. I am using a Windows 8.1 Enterprise ISO as the source. Each time I run the WinToUSB utility it writes to the selected partitions but when I try to boot off that ssd drive I get an error telling me that there is no boot partition and it fails.

You docs do not mention creating the necessary partitions and I using the ssd that was formatted as one partition. I thought maybe your utility would partition the drive for me but apparently not.

Should I try a different win8.1 version? Pro instead of Enterprise? x86 instead of x64?

Hello Sir,

'WinToUSB' is really an excellent and unique piece of Tool for 'Windows to GO'. But we need 'install.esd' too.

Specially I need support of 'install.esd' based AIO ISO Images.
i.e.

Currently I am using DISM method for 'install.esd' based ISOs.

If you convert it into GUI, then It will be more useful for us.

Thanks in Advance

I'm at the forum, it says not to post problems. I'm experiencing problems with WinToUsb and I'd like to report them somewhere please.
