Windows 7: "BOOTMGR is Missing"

sassysarah · 13 Oct 2012

Hi, so here's the case. I know there has been a lot of threads about this but I think I know why this happened but I don't know how to fix it.

So okay, here's what happened:

Recently, I upgraded my OS from Windows XP to Windows 7 Ultimate. However my Windows XP is in Local Disk C: while my Windows 7 is in Local Disk D:. Ever since, I had a dual boot menu at startup. Since I don't plan on ever using my Windows XP, I tried formatting Local Disk C: but it won't let me. So, since i need memory, I decided to delete the files individually including its BOOT folder. It was working until it restarted and told me that BOOTMGR is missing. any hints?

PS: i don't have my windows 7 installer anymore since the CD broke. though I have copy in a USB.

You couldn't delete it because bootmgr and bootmenu were on winxp partition!
do this : Partition - Mark as Active METHOD 2
so mark the Windows 7 partition as active

Now do Startup Repair

Tip

Sometimes it may take running a startup repair (3) separate times with restarting the computer after each time before it fully fixes the startup issue.

Windows 7 boots now? You can delete the winxp partition using disk management now

Follow the tutorial which I listed first, and then we will show you how to make the Windows 7 partition as active.

Alternatively, since you only want the Windows 7 operating system, then you could also do a complete reinstall of the operating system and reformat the hard-drive(s).

You did install Windows 7 previously... how did you do that without Windows 7 install dvd?

You said you had the Windows 7 stored on a USB drive, therefore you can burn the OS onto a DVD using a different computer if available.

Clean Reinstall - Factory OEM Windows 7

The first few steps will allow you boot from the USB drive, and then perform a Repair Install.

Hope this helps,
