Boot Mgr Missing

[Haywalker]

Hello guys,

 

Recently one of my HDDs Failed, So i took the precautionary measure of disconnecting the drive till i send it for data recovery. but afterwards every time i boot up my PC i got a Boot mgr missing error. which would make sense if the OS was installed on that HD but its not, the OS is running from a 120 GB SSD. And the HDD only contained files like pictures and other documents, no programs or anything.

 

i tried going into the BIOS and making sure the boot order is proper. but even then it wont boot. The only way i can get it to boot from the SSD is if i go into the boot menu and select the SSD.

 

is there a way to fix this issue without formatting?

 

Thanks in Advance

I had kind of the same issue.

I put my HDD in a USB external case. Boot over the SSD then plug the HDD. Then you can remove all of windows leftover on the HDD.

In my case, I had an OS installed previously on the HDD.

you can use a windows install drive and choose repair your computer or you can use something like easyuefi https://www.easyuefi.com/index-us.html

First check if the drive is the first boot device in bios. If so, you need an installation disc or thumb drive to boot off. Once inserted and booted into install, click repair your computer. Then click troubleshoot and go to advanced. On advanced try automatic repair or startup repair if listed.

i dont know for sure, but maybe an issue with 1 MBR AND 1 UEFI based partitioning.

currently having an issue like this, bios shows dvd drive and mbr disk but not the uefi disk, however windows 7 recovery sees both and then gives a warning about the uefi drive.

 

as im trying to rebuild this computer and run into some trouble ive used disk part to clean and convert the drives to both mbr based. (just cos i can and dont like the issues people seem to have with dual booting uefi systems)

Had this issue for a while, but if bootmanager is missing it is possible to boot to the OS anyway. I had a windows 7 install that did that, I just needed to have the windows installer disk in the dvd drive. (Turns out other bootable disks did it) I would get the prompt 'any key to boot from cd' but if I didn't push it I'd boot from the OS anyway.

 

Eventually tried to fix it by wiping and reinstalling, I have no idea if this will happen to others and I have no idea why it happened to me, but I could not get Windows 7 to reinstall. So just back up the drive before you try wiping, which I ignored and regretted. (To be clear, I can install other OSes just fine. Linux Mint and Manjaro and Windows Vista all work fine)
