what OS you run? w7? (11 years old today)
I guessed right, (REDUX 1)
you did slam the PC, with microsoft OS, Windows 7 over XP and not buy HP media kit to do so.
that means the F11 key is NOW dead for ever.
the F11 key will in fact put back XP.(HDD NOT DEAD)
The F11 key runs the XP HP Recovery partition install.
So F11 is useless now, totally,
That leaves your newer W7 media kit from Microsoft?,
I guess you bought the DVD? kit? or bought it online at microsft and burned the USB boot kit? OR Burned a DVD-R disk? (no media stated)
no matter , bought it from MS, the kit is good.
not from torrents and pirate sites (i cant see the media install disk so,.,,,,,,,,,,,,,,,,)
MS stopped selling w7 PRO on
November 1, 2016 (home ended 2 years before)
as seeb gere
but boxed sets are still sold on fleabay, NOS
new old stock exists.
so bad big battery out. GOOD ! keep it out.
at 11 years old PC we put in a new RTC coin cell next. after all it's at end of life, and our job is to extend life to the max , no?
next we test the HDD. (next) ask how,
if smart tests fail now, that install media will fail.
like a bucket of water with holes in the bottom can not store water, your HDD is no good, if smart tests tell you it has HOLES( the HDD is Toast)
