Specs: Windows XP, 2.699 GHz / 759 MB
I'm trying to dual boot windows 7 on a second partition on my internal HD, but I am trying to install it FROM an external HD. I googled instructions on how to install, and followed them, but when I try to boot from the external HD to install, I get a "NTLDR missing press CTRL ALT DEL to restart". What am I doing worng?

On a side note:
My external HD is usually used for backup, so there is a folder in the root named backups that I kept there before extracting the Windows ISO to that drive. (the drive is big enough to hold the ISO and the backups with room to spare). Before storing the backups on this drive, I did mark it as an active partition and reformat it. I am assuming that thses pre existing files on the drive have something to do with my problem, but not positive. Any suggestions on how to boot/Install from this external HD WITHOUT reformatting and deleting these backup files. (There is not enough room left on my existing HD to temporally copy them)

Another added note: The external HD I'm using was once the original Internal HD with WinXP installed on it at one time. When I formatted, i just did a quick format (through windows)

You need to make the USB drive bootable and your computer has to be capable of booting from a USB drive.
Here's a link to how to create a bootable USB drive

3 comments on this original question.

1. Before i made my external HD for backups I reformatted it like all other instructions said. I just then added backup files to it before extracting the ISO to it. That shouldn't make a difference right?

2. I recently noticed that it is formatted in the NTFS file system not Fat32. Maybe thats my problem. Is there any way to convert it to Fat WITHOUT losing my existing data?

3. I also noticed that it will work if it try to install windows 7 from WITHIN XP. I never went through with it out of fear of it just installing over XP (upgrading) and not being able to dual boot XP and 7. If I do install from within XP, would I be able to dual boot?

You should follow the instructions and then copy files to the drive.

If you want you can get this all on a cheap flash drive.

First do a compatibility check from Microsoft's site. And download drivers for your hardware (to a USB stick).
Second, if compatible, you will need to install more RAM. You show 3/4 Gig RAM approx. but Windows 7 I believe needs Minimum 1GIG and really needs 2 Gig's RAM - Look into if you laptop will accept two 1 Gig sticks of RAM.
Third, do you already have a second partition ready for the install? If you do not, you will need a third party partitioning tool to shrink your current partition, and create a new one. Windows 7 (not upgrade disk) disk can format the new partition but not shrink the old one.<<<Assuming you have enough room left on your hard drive>>>
Finally, you need to make your DVD drive bootable in your BIOS, put the disk into your drive, and restart. This will then boot to the Windows 7 disk. YOU MUST CHOOSE CUSTOM if you do not want it to install over (delete/format) your Windows XP. Then you can choose the drive to install on, and set up the dual boot.

If you do not have 100Gig free on your hard drive (If you have say 100 GIG free, the 100 GIG does not and should not all be on the new partition), you will find it very difficult to do this and difficult to run though. --- Is there any reason you don't just switch over to Windows 7 completely? It would be much easier (assuming all drivers are available and downloaded onto a flash drive) than the dual boot path. Do you actually need both?

I did and it worked for me. When you're choosing installation type, be sure to select Custom (advanced) and choose the partition you want for Win 7
