Installing XP on external harddrive Tags: Windows XP Command Prompt Hard Drives External Hard Drive Last response: August 15, 2010 6:48 PM in Windows XP Share jt101 August 14, 2010 10:59:21 PM Hi all I'm having difficulty installing windows XP on my PC, so I've removed the harddrive and have connected it to my laptop via USB. I found a website which suggests putting the followng in the run command: "Assuming the hard drive is "D" and the XP cd is in "E:", go to the run command and type (or cut and paste): E:\I386\winnt32.exe /syspart : /tempdrive : /makelocalsource /noreboot" The problem is the laptop is running off VIsta, so when I try to do this, it gives me the following error: Setup cannot continue because the version of Windows on your computer is newer than the version on the CD. Anyone got any ideas how I can get round this? THanks More about : installing external harddrive aford10 August 15, 2010 2:49:14 AM Are you trying to install windows from inside windows? You need to change the boot order in the BIOS, and boot off the CD/DVD drive. tigsounds August 15, 2010 6:19:00 AM Quote:Anyone got any ideas how I can get round this? You're going to have two messed up computers soon. You should not jeopardize your Vista computer trying to install XP on another drive connected to it with the intent of putting the drive back where it came from once XP is installed on it.. Put the drive back in the computer it belongs in and describe the problems you are having installing XP on it. Someone here will know what to do. Can't find your answer ? Ask !
