I have this really old system , like 2006 or something. I still use it, only for queuing online downloads. It hasn’t been giving many problems as such, other that the slow processing speeds. Not so long ago, the Windows XP on this system crashed. Formatted and reinstalled XP, which crashed again. Then I thought of installing Windows 7 from my pendrive (I don’t have an “IDE” DVD DRIVE, just a CD writer ). But my plan hit an instant road block, as there was no option in my BIOS to boot from USB drive. It’s a PHOENIX 865M05LZ v1.04 release date : 11 May 2005. A bit of searching got me this application, PLoP Boot Manager So I burnt a bootable CD of the same , connected my bootable pendrive and followed the procedure. But to no avail. The problem which I observed was, the pendrive was not getting any power at boot – as indicated by no glow of the led on the pendrive at boot. Is there any method available to boot off a pendrive on my current system ? And, NO ! I don’t wish to purchase an IDE DVD DRIVE (none of my friends have it either.) just for this. No computer vendor in my vicinity would flash a BIOS.
