BOOTMGR is missing after setting new partition active

Ok, i screwed up bad. I didnt know what i was doing i guess. Now, i cant get into the computer, and i have no recovery cd, or windows cd they got lost. What can i do? Also, my next door neighbor dvd burner does not work. Is there anything i can do? I thought i could go into command promt by pressing shift f10 but it dont work. Some how i believe if i can set the windows 7 C drive active, , it will boot up again, bu tthe screen is at a stand still all i have the option to do is keep rebooting. Please help with a response quick because he has to leave with his computer.

Hello rwalkerfla, and welcome to Windows Seven Forums.

If your system has the 100MB "Reserved System" partition installed, you have some repair options accessable at boot:

If not, then I am sorry to say it is time to find a way to get some utility CD's or a new Install DVD?

Cheers!
Robert

Yes i do have it i remember for sure, but when i boot up, all i can do is hit f2 for setup, hit f12 for boot sequence, ore restart. Thats it. All it says is bootmgr is missing . presee control alt delete to restasrt. That screen your showing is not available. What do i do?

If you cannot access the Repair console by tapping F8 during bootup, then You will need the System Repair CD to use Diskpart commands to mark the Windows 7 partition active again, then possibly need to run Startup Repair up to 3 times with reboots to repair MBR.

Boot Repair CD, open a Command line and type this to set Windows 7 active again:

DISKPART
LIST DISK
SELECT DISK # (# for Windows 7 disk)
LIST PARTITION
SELECT PARTITION # (# for Windows 7 partition, or 100mb System Reserved partition if you have it)
ACTIVE
EXIT

This may start it, but if not you need to reboot the Repair CD to run Startup Repair up to 3 separate times with reboots to repair or rewrite the MBR.

Hi rwa,

Best thing is to d/l one of the Paragon freebies - on your friends machine.

Backup & Recovery 10 Free

B&R10 Free Registration


Get the free key they email you . Install it. At top left of main Paragon window, click Tools >Recovery media builder. Select the option for flash drive and it puts the recovery program on flash for you.


Plug that flash drive in your machine - go into bios and set usb as first boot device. Restart.

Select Normal mode ( Safe Mode if you have a problem with Normal Mode).

Rt click the 100mb partition and mark as Active.

( If you don't have 100 mb partition , mark 7 partition Active instead.)

APPLY.

Restart. Fingers crossed.



Hi iseeu.

Sorry , that is the problem with that option. It relies on accessing bcd. It is subject to many of the same startup issues as windows itself. It is not a substitute for having bootable recovery media.

As your DVD is working, try startup repair.
