Follow this guide (Slipstreaming Driver using nLite)
FYI, you can burn it as image, then use virtual drive as Daemon Tools (Download) to mount it
Trying to restore XPSP3 on Medion akoya MD96910 netbook. Worked fine until 99% of files copied then got: Setup cannot copy the file: iaahci.cat - giving 3 options (retry, skip, quit). Retry didn't work so skipped. Similar message for iaahci.inf iaStor.cat iaStor.inf iaStor.sys. Subsequent XP Boot then failed. I do not understand why the intelSATA drivers (these files) won't load. Will try again with Netbook Bios AHCI mode set to Disable but not confident that will make any difference. Help!
Ref: MD96910 netbook restore. With AHCI mode disabled it works without loading the intelSATA files. I assume these will have to be loaded, just got to figure how to do that now! Thanks for great install guide - brilliant. If you could put a comment about intelSATA it would be great, I cannot be the only person who doesn't understand it.
PeToUSB didn't find any removable flash drive. Please help me.
by the way, I'm using Windows Vista.
Try use XP... or
use another USB port... My friend tried it on his Lenovo... when he plug in his USB flashdrive on left side of his notebook... PeToUSB didn't find any removable flashdrive... he change it to the right side then it works (XP) :)

Easy and well written.. thanks for making our lives easier. Although I should mention that I've tried it inder Windows Vista at first and the USB Flash Driver wasn't readable at all. The whole process must be under Windows XP. Again thanks, and wish you all the best.
I was having the "No USB Disks" error with PeToUSB as well with by Samsung U3 (2G) and my microSD + Reader (4G) on 32-bit Vista. The USBs were all formatted to FAT.
Then I switched to XP, and the USB was detected
I want do this is Vista...

If you're on Windows Vista, try using the "Run as Administrator" function for both formatting the drive and command prompt.
thanks for the instructions works like a charm everytime :D
got one question though, can you use partition manager to make partitions after XP has been installed successfully using this method?
Like Obama said... Yes We Can!
For more FAQ, please read comments section.....
Hi Guys this is greate blog Guess what i sued the same instruction to install the Server 2003 sr2 and works well for my Home server
Thanks to you all the Contributor
Everyone please read this WinToFlash Guide - Install Windows XP from USB Flash drive
NOTE TO ANYBODY WHO'S FLASH DRIVE CANNOT BE DETECTED... If you are in Vista or Windows 7 (Like Me) you have to Right-Click PeToUSB.exe, go to Properties, Compatibility Tab, and in Windows 7, choose RUN IN COMPATIBILITY MODE, and select Windows XP (Service Pack 3).
In Vista, just do some kind of "xp" mode. Also, in Windows 7, Command Prompt will probably give you a "denied" message on one of the "CMD" commands. Before going into Command Prompt, Right Click it (When typing into the search box in start menu) and click "Run as Administrator".
