Boot hp pavillon zd8000 with usb not possible?

and last, for legacy, machines, (thesis)
how to boot to uSb but Phoenix cME first BIOS Pro Setup Utility, wont let you.!

read this, (a super pain it is)or just tedious.
(lacking DVD drive that holds, w7 installer)
you never said if the original OS was dead
nor what it is/was? XP? /vista?


way1:
if XP/vista runs, then insert the w7 USB stick
and click setup.exe on said stick,.

way2.upgrade the bios so it can do usb boots.
oops this method is long long gone now, for 15years. (you be way to late here....!!!)

way3:
using a CD disk; (this is very tricky but works)

way 4: (w7 is 3.3 GIGABYTES large)
W7 does not fit on any CD made, ever.
s0....
Buy a DVD drive upgrade for this relic PC. (not easy to find and chose) then
burn the W7 ISO to the DVD using any DVD burner.
do so using RUFUS (free) or microsoft free burner app. at microsoft dot com.



way5: (force feed way)
this is a very very tricky way, I will not tell you all steps, as you will get lost.
and is not authorized by MS.com.
Short as possible to say , below.
We have 2 machines here, 2 PC.
your dead PC and the donor or Test PC.
find a good test PC, any PC that uses the same HDD drive type as yours does. (IDE{PATA} or SATA)
this old dog PC is PATA, and most other PCs no longer have PATA ports, making this a pain to do. (I can but I have adapters to do this)
Remove the 100GB hdd (pata) from the old PC
Remove the test machines HDD.
if test machine is SATA you need and adaptor.
ask.
connect the old HDD to the test machine.
have no other hDD in the test machine now.
if present unplug them.

then insert, w7 usb, and boot to USB using
the hot key stated in the test PCs manual.
on HP its F9 hot key.
now install w7, (end to end ,means many boot cycle as all installs do...)
done.
now remove the old machines HDD from test PC.
and put this HDD back in the zd8000 dog PC.
boot the HDD, in this PC.
w7 runs now.
and will be very angry. (fear not)
if will try to find missing drivers max.

in most cases if you are skilled and get
the WAN working, ETHERNET CABLE connected to a router, then the new PC HDD will find said drivers at microsoft servers. and things start working.... inch by inch.
next if you can down load all all drivers from HP, for this PC, oops they are now gone
the PC is too old for HP to support it.

we can in many cases find each missing driver by the hard way. ask.
in some cases the chips how have inside a super old PC like there never once had a w7 driver,ever.
I can list 100s of examples but I STOP HERE.

Better way 6? (captain obvious sorry)
buy a newer PC, 2010 or newer,
that runs w10-64 and WIN.
spend over $20

I forgot to say
I do full HDD tests on any hdd before loading ANY OS, or the load will fail. facts of life.
I run full SMART tests on it,(crystaldiskinfo)
never seen a good 15 year old HDD yet.
1/2 working sure, but not fully. (fail you will)
for sure on crummy laptop HDD.
there are far better choices. like SSD. I forgot to say I do full HDD tests on any hdd before loading ANY OS, or the load will fail. facts of life.
