Installing Windows7 from USB
I finally figured out what was going wrong when I tried to install Windows7 from USB. I did the following:
I mounted the Windows 7 Beta ISO using Daemon Tools on a Windows Vista machine. I then followed the following steps for my 16GB USB key:
- I opened a command prompt with administrator access. I did the following commands:
select disk 1 (that happened to be the disk number of the usb key, might be different for other people)
create partition primary
select partition 1
- I then copied the files from the mounted ISO image to the USB key using the following:
xcopy e:\*.* /s/e/f g:\ (E happened to be the virtual DVD drive, and G happened to be the USB key drive letter)
My problem is that in the BIOS for my P6T motherboard, there is not a separate option to boot from USB. The USB key has to be set to emulate a hard disk or CD drive, and that then has to be set to load before the real CD or hard disk drive.
I ran into another problem the second time I installed Windows 7 (I am on my third installation, as I tinker with the partition set up I wish to use). I had used the USB key on a Mac, and it changed something so the key was no longer bootable. I had to go to a PC and follow the steps outlined above all over again. Those steps take about 30 minutes to complete – no real big deal, since I can do other things in the meantime.
