BOOTMGR is missing

EasonIDontKnowAnything · December 3, 2022

Hey guys. So I'm using a SSD as my boot drive with Windows 7 on it and a HDD for my storage. The new HDD I just ordered to replace the old one arrived today and I promptly plugged it into my computer. However, when I try to boot my PC, it shows "BOOTMGR is missing". I've made sure that the SSD is my boot device in the bios (you can refer to the picture) and it was working just fine yesterday, so I'm pretty puzzled about what the problem could be. Help would be appreciated :)

This is what shows up if I unplug the new HDD and try to boot with just the SSD

The boot manager is probably on the old hard drive that you replaced. One of the extremely annoying things that windows will sometimes do, and I always recommend installing windows with only a single storage device installed.

I hope that's the only issue.

So, um, how do I install the boot manager on my SSD? Thanks.

You are right about the boot manager being on the old HDD, btw. Thx for clearing that up

I have not done so myself, but this guide might prove useful

Sorry for bothering you again but I still need a bit of help, if possible? Don't know who else to ask and I'm not too sure about making a new post.

I tried the command prompt shown on the page but it didn't work. It still says that the boot manager is missing when I unplug the old HDD. I did a little bit more searching and came across this thread from someone who had a similar problem as me, but unfortunately I don't really understand the answer all that much...

Do I need to partition my SSD for this to work or something?
