Fix windows 7 boot after windows 8 install

[anything I don't mind]

I installed windows 8 on to a second hard drive, as i thought i would give it a go. I soon changed my mind and took the drive out of the pc. But it has now caused problems on my windows 7 install.

When starting up it comes up with a windows 8 repair boot error message and won't boot. I have to press the boot menu and then specify the windows 7 disk for it too boot. Don't know where the MBR is on. Is there any way to fix that without having to put windows 7 on to the usb stick and repair the install.

Second problem is that when starting windows 7 it wants to check every disk in my pc which is a lot of disks and i would not let disk check run on those disk, as there is no need to run it. Is there any way i can disable these disk checks as its annoying to have to press skip on each disk every time i boot.

edit: ok i fixed the boot problem with windows 7 usb. But still getting the disk check every boot.

Worked in the past, no need for me to retype when ctrl v will do it

"Click on Start then Run , type cmd and press Enter . Next type fsutil dirty query x: where x: is your boot drive. This queries the drive, and more than likely it will tell you that it is dirty.
Next, type chkntfs /x c: . The X tells Windows to NOT check that particular drive on the next reboot. Now manually reboot your computer, it should not do a chkdsk and should take you directly to normal Windows login.
Once Windows has fully loaded, bring up another Command Prompt and enter chkdsk c: /r . Reply Y when asked if you want this to happen on the next boot. This should take you through 5 stages of the chkdsk scan and will unset that dirty bit. This can take an hour or more depending on the size of your hard drive, be patient and let it complete.
Once booted back to Windows, open another Command Prompt and query the dirty bit again by entering fsutil dirty query c: and Windows will confirm that the dirty bit is not set on that drive."
