cant reload my os

i have a hp pavillion 300 desktop,I have just changed the harddrive,(to a bigger one)and wish to
load a new os on it. the hard drive I installed was used,but good,I can not seem to get the computer
to boot from the dvd rom.
i went to bio screen to the boot section,it show floppy drive,hard drive and adapti cd rom
when i push enter on the dvd rom nothing happens,I was able to move it to the top of the list,but no
change.
there is + next to the floppy and harddrive,but nothing next to the dvd rom.
is it not seeing the dvd rom?


it is a burned copy of windows 7 on dvd,
I dont know about the drivers for the dvd rom,but the harddrive is new to the machine,but used.
windows 98 tries to load,,must have been on the harddrive before i got it


also, after the windows 98 screen comes up,it says c:\>
thanks again

bios screen shows as follows:
boot device priority
atapi cd-rom
removable devices
hard drive
here is the thing,there is a HP cd writer and a dvd-rom in the tower,no cd-rom
i dont understand what the atapi cd rom is listed for.

I also tried unhooking the harddrive and floppy,hoping to force it to boot from dvd
no luck
please help me

 

I have sen this happen with burned dvd's, when the dvd drive does not like that particulaar type of dvd, or, it is a bad burn.- It then see's the dvd drive as a cd drive.
I would use your originl XP, or, Vista cd/dvd to format the 'new' hard drive,-- and even load a Vista on to the 'new' hard drive, and don't bother registering it, but once installed, just insert your W7 disc in the dvd drive and install it through Vista- in other words instal directly while Vista is up and running, as it ill instal that way, if the 'burn' was good- I am assuming this is a legal burn, and not pirated, as we cannot condone pirate dvd/cd 's.

Re: cant get my operating system to reload

quick guess is your 'burned copy' is not a bootable disk. Depending who / how the disk was made the boot section may not of been copied. Will it boot in another PC? You did move CD to the top of the boot order? Your not getting a "press any key to boot cd"?

 

I am not getting the press any keyto boot from cd,
I think i have moved it to the top of the list.
I may have a drive issue,,i tried a factory xp disk /same ,same
thanks
