tried that already bro, It needs a blank bootable Diskette that doesn't exist right now!! actually it exist physically but i need support for the USB bootable part things!! any answers?

Make a bootable usb or dvd then.

Why can't you download and install it from your pc?

Just to be clear I'd already had the latest bios file from DELL This pc has no OS yet so i get a BOOTMGR is missing but i know i need an os for that!! This bios file goes into my bootable usb but when i plug the USB on the pc and turn it on, it just didn't show my USB?? What supposed to be the problem!!

Have you set your usb as first boot priority in bios?

 

[GTALCASystems]

There's nothing there!!! It's only showing the CD/Diskette/HDD drive!! Im not really good at older systems so i'm looking for help!!!

Got a Windows disk then?

 

[GTALCASystems]

What Disk? You mean the OS yep i got 4, xp, vista,7,and 8 or the Recovery Disk? on Dell nope on Os yep windows 7 recovery disk

 

[i7Baby]

What happened to the OS that was on it?

Have you tried installing using any of the Windows disks? They all legit?

If you can't, you probably need a Dell installation disk.

I Accidentally turn off my pc when it's installing so that's the reason the OS was gone!! Well i used these OSes many times!! BTW let's get back to the bios when i choose what to boot in the bios menu the USB didn't get listed?? any Solutions??

 

[i7Baby]

Use your OS disk. Make sure the ODD is the first boot priority.

your not getting my point bro!! my problem was the bios not the OS!! my bootable USB, It wasn't there on the list in the BIOS boot menu, The only one's showing was 1. Normal 2. Hard disk drive C: 3. IDE CD ROM Device 4. System Setup 5. IDE Drive Diagnostics 6. Boot to utility Partition!!! NO USB, even if my usb was bootable!!

Go into bios by hitting F2. Look through all fields for "boot from flash drive" or "boot to USB". If that doesn't help, post here and I'll dig my dell Gx260 out and do what I can to help.

 

[Cameronmotes]

What I meant was, make sure inside bios, it's enabled to boot from USB drives.

 

[GTALCASystems]

Well it seems to be the problem was solved! The Capacitor blowed that i needed to junk it....
