You can install Windows XP on a USB pen so that you can troubleshoot problem or take your office with you. From the article:
All it takes is a minor error in the Windows Registry or a virus infection, and your operating system can become unbootable. But with a properly configured USB flash drive on hand, you'll always have a compatible replacement no further away than your pocket or keychain. In addition, the flash drive can also provide a secure browser and virus scanner, and lets you take your favorite DVD burning and Office software with you wherever you may go
All that's needed is a bootable USB Flash drive with at least 256 MB of storage capacity and a Windows Setup CD. Using the program Bart PE Builder (Freeware), you can install Windows XP on the flash drive, along with other software as needed (and as available space permits)...

I do not have a hard disc in my PC. CD-ROM is working and I have Win XP SP2 installation CD. I want to utilize my 4 GB pend drive as hard disk. Can I install win XP SP2 in my pen drive? Whether my system will boot properly. My BIOS shows that it can boot through USB-HDD. Plz suggest.
NO SIR, IT WON’T WORK! I TOO HAVE ALREADY FACED THIS PROBLEM 7 I EXPERIMENTED WITH THIS ISSUE. IT’S A WASTE OF TIME. SOMETIME THAT OS MAY INSTALL BUT IT DOESN’T WORK….
BETTER BUY A NEW HDD OR TRY TO MAKE USE OF ANY OLD USED HDD. YOU CAN BUY SOME USED HDD IN ONLINE SHOPPING SITE LIKE “ebay” OR I THINK YOU CAN INSTALL IN A EXTERNAL HARD DISC TOO! I HAVEN’T EXPERIMENTED WITH EXTERNAL HDD, BUT THERE ARE MORE CHANCES FOR THAT…
