Alan is correct, saving backups to an external drive is better.
If you save backups on the C: partition, and xp fails to boot, you (probably) won't be able to get to them to restore them.
I say (probably) because the rescue disk might find them even though win xp has failed. But thats not a risk you have to take.
You can either create a new partition on the main HDD or, better, get an external drive as suggested above.
I store backups on a user created partition on the computer's HDD and also on that external USB HDD I mentioned above.
Here is a screenshot showing the partitions on this computer. Open it in a new tab to make it larger.
On this computer, the C:\ partition is 45 gb, more than enough to run win xp.
The V:\ partition is about 102 gb, all the space I had left.
The V:\ partition was created using Acronis Disk Director, but MiniTools Partition wizard will do the same thing and it is free I have used both with success. You can also use the built in windows disk manager but I never have. Had no reason to.
What you see in the bottom center of the screenshot are the backup files, with the .tib file extension. As you can see, they are quite large files, another reason to get an external drive if you can.
Edit: I was typing this when you posted your last. Will just add this. All this stuff is easier than it sounds or looks.
I have absalootley zero real world professional (as in paid) computer work experience. Know almost nothing beyond what I have learned here and on a few other internet sites. Minitools Partition Wizard is just a CD that you boot up to and make your partitions. Macrium Reflect is free and lots of folks here use it and could help.
So you could do it yourself, and gain the peace of mind of knowing you don't have to depend on the computer shop.
