Destroyed BCD with Linux Mint

if you could get into the elevated cmd promt you could repair the MBR using a repair disc

Type "Bootcfg /?" (minus the quotes) in the Start/Run line to see the commands available that way. Note that the /Rebuild command isn't available from inside Windows; you can only run that from within the Recovery Console. (That makes sense because you only need to totally rebuild the boot information when Windows won't start normally.)
A /List command is also available only from within Recovery Console. It simply lists the entries already in the boot list, which can be useful for checking or as a learning tool.

My suggestion to everybody who wants to play around with Linux and see what it is all about, USE VIRTUALIZATION software.

I've lost count of the number of times that I've seen a Windows user who wants to play with Linux, who puts it onto their machine as a dual boot, and ultimately finds out just how different it is, and then quickly decides it's not for them and wants it removed. And the problem is always that Grub is the bootloader now. You don't run into these issues when you run in a virtual machine.

For somebody like me, who supports Windows and Linux, I want a dual boot on my laptop. And I'm 100% happy with having Grub as my bootloader. It's never caused me an issue, and I won't be deciding that I don't want Linux on my laptop anymore.

I don't want this to sound harsh...but please consider running a virtual machine when you want to try Linux and don't immediately jump to dual booting. I know lots of people scoff at virtualization because they cannot do the fancy whiz-bang compiz graphics stuff in a virtual environment. But I'll be honest, if you are new to Linux....you likely aren't going to stick around long enough to get the fancy graphical stuff going anyway. Just sayin :)

Startup Repair: frequently asked questions http://windows.microsoft.com/en-US/w...sked-questions

Start your computer from a Windows 7 installation disc or USB flash drive http://windows.microsoft.com/en-US/w...SB-flash-drive

Thank you. I already got this CD. It is what I meant with Recovery-CD from USB (since there is no cd-drive in the machine I had to put it onto USB). I already tried the "Startup-Repair", but it did not help. It said that there was an error in the partition table, and it was corrected. Did not help, though. Then I tried the command prompt with bootsect, diskpart and bootrec with the corresponding options from the tutorial. But with /fixboot it always says "element not found".

Edit: "bootcfg /query" (the list command you mentioned above) responds
"ERROR: Cannot open BOOT.INI file."

have you a live cd with ubuntu on by any chance? and know a friend with a external cd/dvd drive you can borrow? so you can boot from the disc live into ubuntu?

because if you can get into windows with linux you possibly will be able to repair it

boot from the stick and see if you can see the drive that has windows 7 on to start off
