Deleted system reserve, stuck, cant boot

I wasnt thinking and deleted the system reserve partition when formating to windows 7. Now I cannot boot at all. It is an asus laptop. It is stuck on the Asus screen and nothing happens. I cannot even go into the bios, nor can it read the harddrive or dvd drive or usb. is there a solution to fix this problem?

Deleting a partition shouldn't have anything to do with the ability to enter the bios. You can enter the BIOS when you don't even have a hard drive attached.

Since you can't boot into the drive, you'll need to use a LiveCD to boot the system. Then you can use the TestDisk utility to attempt to recover the lost partition.

Download and make a LiveCd from one of the following:

TestDisk Livecd - CGSecurity (Ubuntu Rescue Remix should do just fine if you don't have a favorite)

Then, run TestDisk accordingly:

If you can somehow get it to boot up, Microsoft has a method of recovering deleted partitions as well:

i thought that it shouldnt affect the bios either, but for some reason, I cannot boot into the bios, would it have anything to do with the cpu battery?

You said you deleted SysReserved when formatting to Windows 7. If you formatted the HD to install or reinstall Windows 7 then it shouldn´t affect booting the installer.

If you´ve truly formatted to install or reinstall, then the DVD should autostart if in the drive. If not try using the one-time BIOS Boot Menu key given on first screen. Do you get the prompt to "Press any key...?"

If on the other hand you mistakenly deleted SysReserved and have Windows 7 still on the HD and needed to boot, you can either recreate SysReserved by using free Partition Wizard bootable CD to create a new Primary Partition in the space, mark it Active, then boot the Windows 7 DVD Repair console or Repair CD to Startup Repair - Run 3 Separate Times to rewrite the Sys Reserved partition.

The other method is to instead mark Windows 7 partition itself Active then do the 3 Startup Repairs. You can also use PW CD to resize Windows 7 into the old SysReserved space.

If the ASUS screen you mentioned is what I think it is, that is the BIOS. My ASUS motherboard flashes a ASUS screen listing the BIOS key options at the bottom, like press DEL to enter BIOS setup, etc. It also lists the key to press for the quick boot menu. If it's freezing at that screen there is something else besides a deleted partition going on. Unplug any external devices like USB external drives, and try again.

actually i think the system reserve has nothing to do with it, but basically it will not boot into bios, it just keeps restarting on the ASUS screen which doenst even get to the part where it loads and says which key is bios key.. i think there is some hardware issue

Yes, I agree, it sounds like a hardware problem, boot issue. Thats why I suggested unplugging any external devices. External USB hard drives are known to cause this situation. If it was a desktop PC I would recommend reseting the BIOS to fail safe defaults with the clear CMOS jumper. On a laptop that is very difficult if not impossible to do. Remove the battery and unplug the power pack, then press the power button to completely drain any residual voltage. Then try booting it up again. If that doesn't work you may have to remove the optical drive and or the internal hard drive and try again. I'd probably re-seat the RAM modules too. If it still won't boot after that I don't know what to suggest.

Can you please clarify exactly what you did since you have not made this clear at all. You said you deleted the System Reserved partition when formatting your HD. But formatting deletes everything anyway. Did you mean that you deleted System Reserved mistakenly? I have now asked you this twice.

We can help you fix a deleted System Reserved partition by either replacing it or marking Windows 7 partition Active to run Startup Repair 3 times. We do this here all the time, but we need you to be clear on what you have done.

We can also help you boot the installer to reinstall if that is your problem.

First try tapping the one-time BIOS Boot Menu key at boot:
Asus - F8
HP/Compaq - Esc
Sony - F2
Acer - F12
Gateway - F10
eMachnes - F10
Toshiba - F12
Dell - F12
IBM/Lenovo - the blue Thinkvantage button

Do you get the prompt to ¨"Press any key to boot DVD/CD?"

actually it was having boot issues before, but would randomly be able to boot into windows.. thinking that there was something wrong with the OS I reformatted the computer.... and now it will not even boot up at all. but i dont think it is a OS booting issue, but more of the hardware issue becasue it just gets stuck on the Asus screen, and cannot even jump into the bios settings, or choose to boot from any options..

also i do not have any externals plugged in, or any usb hardware. I have reseated the ram before, but i think i may try without the optical and harddrive to see what happens, if anything ill try and remove the cmos battery, or maybe the cmos battery needs to be replaced...

i do not get any prompts because any of the bios shortcuts, or booting shortcuts dont work.. it just stays on the ASUS screen, the screen restarts every so often though
