If I remember correctly, I said I went thru the many links in hopes of trying to find out how to change the boot order of this XP so I could boot it from the USB but despite others help & my own looking, I never was able to & came to the conclusion this Systemax desktop is built differently than a Windows XP so why try something that may not work.
Somebody else suggested using a CD, but I asked myself, if it can't be booted from a USB, it can't be booted from a cd. Long story short, if somebody out there has an IDENTICAL Systemax desktop pc & can help, fine.
Yes, I have started some threads in here & never finished them but too late now since it crashed.
I do the best I can but when I can't find something a helper tells me how to look for it, sorry for my ignorance.
