"BOOTMGR" missing... installing Windows 7 on SSD in ACHI mode; new mobo

post #1 of 2
Thread Starter 
Hey guys, I was just trying to install Windows 7 ultimate 64bit onto my old SSD drive in ACHI mode on my NEW ASUS Z87 Sabertooth motherboard.

It's one of those "upgrade" CD's for Windows, so I needed to install Windows XP first in IDE mode (I used the QUICK FORMAT option)

I then proceeded to install Windows 7 and switched BIOS to ACHI mode.

Upon install, I rebooted to the Local C:/ (SSD) drive that now had a "fresh" install of windows but it said "BOOTMGR IS MISSING".

I was a bit shocked. I was able to boot into windows somehow but setting my BOOT OPTION #1 to a different SSD , which was incredibly weird for me....

In windows, I noticed it didn't even show 1 of my SSDs ( I have two)

ANYWAY, long story short, I re-installed Windows 7 to that SAME SSD to try again and NOW IT'S WORKING PERFECTLY IT SEEMS.


I am just trying to figure out what the hell could have initially caused that, since, I just JUST purchased this new z87 ASUS Sabertooth mobo and I'm trying to troubleshoot to make sure it wasn't any of my gear.

Does anyone have any input?

When another drive is connected to the system during installation, BOOTMGR (and other things like it) are placed on that drive instead of being placed on the drive you're installing Windows to. So, when you switched the boot priority after installation, you changed the way it was set up. If you had put the boot priority back to the way it was, then it would have worked without reinstalling Windows.

For this reason, remember to never leave other drives connected when you install Windows 7.

Also, you didn't have to install XP first. For future reference:
