Trying to save drive and XP

[1robert]

 I live in Spain BUT require answers in English please.
 Following a massive problem with a virus I had my C;\ designated 100GB drive cleaned.I reinstalled it as a SLAVE to a 20GB drive to which I loaded ny original Windows XP CD.This went smoothly,all Updates [24 plus IE7] and the system is working -slowly and with less associated programs in C;\. C:\ is 65% full and F:\[with data only} has less than 20%.
 I would like to transfer the physical drives-then have a single drive with Windows XP [that being my original -now cleaned -drive.I would of course make it the Master and disconnect the 20GB drive.
 I have no idea which(OR EVEN IF0 this option is available.
I am intimidated by xcopy and anyway am not sure how to get to DOS--I am too nervous[at 73 years old!] to risk trying a folder transfer without your advice.
  The last computer hardware I worked on was Univac 1050-II in the USAF -in the 1960's.
PLEASE ASSIST

This looks like an English Forum.....
Anyways, Welcome to ComputerHope.

I don't think I quite understand the situation.

You have to Hard Drives. One 100GB and the other 20GB. You want to somehow merge them into 120GB?

 Probably my poor explanation.
I had 2 hard drives-C:\ was a normal Master [100GB]with Windows plus all everyday usage.The second was an emergency back-up[20GB] mainly for critical .duplicate, photographs so that if I had a catastrophic failure I could physically remove one drive and save them.
Due to a Virus9my first ever0 I removed the 100GB drive and had it cleaned up.During the wait for this I loaded my original XP CD-ran all updates -also installed IE7 and this was sucessful BUT I had only a 20GB drive and few programs loaded. When I reinstalled the 100GB drive-as a slave I was able to trnsfer some data to the newly named C:\ drive but the system is slow and -of course inefficient.
 What I would like to do -and do not know how-is to have ONLY ONE DRIVE-the 100GB drive.
If, for example, I tried to install-using my original XP CD to this drive, having previously physically removed the small disk-what would happen?I assume I would have-somehow - to enter BIOS aND SET THIS DRIVE AS MY boot drive.HOW?
 Alternately can I re-name the 100GB drive[presently F:\] as C:\??
 Or is there a simpler way? The reason I mentioned that I live in Spain is that ALL the computer people here only speak Spanish-are not familiar with an English version of XP and, with all respect for their skills, simply wish to provide me with a Spanish CPU with Spanish Vista and cannot tell me how to save my present data.

I think, your best option is to create an image of 20GB drive, and transfer it to 100GB drive.

To create an image, you can use one of tools listed below:

Acronis: http://www.acronis.com/ - not free, but the best

Free alternatives:
- DriveImage XML: http://www.runtime.org/driveimage-xml.htm
- SelfImage: http://www.excelcia.org/modules.php?name=News&file=article&sid=21
- Macrium Reflect: http://www.macrium.com/ReflectFree.asp

 Thank you Broni for the advice. I am now in trouble again.I reloaded my XP CD to the 100GB drive and all updates and IE7and Windows Live -Mail,Messenger etc.
 I used to receive e-mails to a gmail address and a .msn.com address.  I have been forced to activate a hotmail.com address and am totally unable to restart my old msn .Any suggestions on what I did wrong or how to get out of it would be welcome
I note that my Favourites list ahs also disappeared

Which image program did you use?

I reloaded my XP CD to the 100GB drive

sounds like a clean install...

[Broni]

In plain English, if when you wrote that you "reloaded" your XP CD, you mean that you did a full install, then you have overwritten, destroyed, removed, deleted, erased everything that had been added since the last time Windows was installed.
