I Want to INSTALL Windows 7 RTM using a external hard drive. I do not want to run bootcamp on the external hard drive just install it using windows 7 installation files on the external hard drive.
Just to Clarify I don't want to run it on my external hard drive. After installation i will run it on my internal hard drive. I just want to install it using my external hard drive.
Unless its x64, you should be able to boot off the install DVD and format the external and install but the install will want to reboot off the external which won't happen.
I'm not sure it's possible to boot off of the external drive to start the install.
You can try plugging in the drive and holding the option key when you boot, to see if it shows up as a selectable option.
After the first reboot it doesn't need to boot off the external, all the necessary installation files will have been copied to the internal drive.
The issues are 1) whether the the computer will allow booting from an external drive, and 2) the installation program itself will be ok with this
I realized this after my third post. Doh! Can't do it on a Mac because the install device needs to boot first and Windows can't do this on Macs (EFI?).
