Problems with multi-booting, can't boot Windows 7 anymore


Okay, so I screwed up. I have Linux Mint and Windows 7 installed on my laptop, and recently tried tinkering with EasyBCD, to use the Windows multi-boot loader instead of grub. Well, that didn't work out too well, because I ended up with the Windows boot loader with two options, Windows 7 and Linux Mint, however the Linux Mint entry just redirected me to grub, which wasn't what I intended.

I tried to put things the way they were, with grub as the only boot loader, and figured I'd do so by setting EasyBCD to skip the multi boot screen and going straight to the Linux Mint entry, which corresponds to grub.

Well, now when I boot, I get the grub screen, but if I select the Windows 7 entry, it just redirects me back to grub, so I can't access Windows 7 right now. What can I do to fix this? Can I edit the Windows boot loader from within Linux?

Cheers

Fix mbr using the windows cd.

After this, use only one bootloader, if you happy with EasyBCD, go for it, otherwise Grub is a good choice.

I don't have the Windows CD with me, so that isn't an option right now. Isn't there a way to rewrite the BCD from within Linux?

Okay, so I managed to solve the issue, and can boot Windows 7 again. However, I still have the same problem. When I boot, I arrive at the BOOTMGR screen that asks me to choose between Windows 7 and Linux Mint. If I choose Windows 7, it boots normally, if I choose Linux Mint, it loads Grub, again with the options of Linux Mint and Windows 7. If I choose Linux Mint, it boots normally, if I choose Windows 7, it loads BOOTMGR. I want to eliminate one of the bootloaders, to eliminate redundancy, and save time when booting Linux. How can I do this without screwing things up like I did last time?

Not sure that reinstallation is what you require. What is happening is that you have two config files, one Grub, one EasyBCD, and one of them, presumably the latter, references the other. For example, I installed OpenSuse 11.2 with Grub, the config file being /dev/sdb8/boot/grub/menu.list. I then installed 11.3 on /dev/sdb6, again with grub. This is the menu which first appears, but if I select 11.2 it displays the old menu If I look at /dev/sdb6/boot/grub/menu.list, one of the entries is

root (hd1,7)
configfile /boot/grub/menu.lst

I don't know EasyBCD or where it keeps its config file, but maybe the answer is to remove the grub config file, probably called grub.conf in your system and reinstall EasyBCD, or, if you can find its config file, edit that to boot Mint directly. Alternatively, I seem to remember that my menu screen has an option to merge the menus, does yours? (I'm not going to reboot to check that vague memory!) I must emphasize that any advice above has not been checked and is entirely withot warranty!

Hi,

you don't need an original windows installation CD/DVD.
You should download Windows 7 Recovery CD, burn it, start your PC by booting from this CD, Select the Windows console, type following and press "Enter" after each command.

# 1st command
Bootrec /FixMbr
# 2nd command
Bootrec /Fix Boot
# 3rd command
Bootrec /Rebuils Bcd
# 4th command
exit

You can also use the automatic solution but it will do the same and will take much more time.

Enjoy

Listen to EDDY1 - Take your live Mint cd and reinstall grub. Here is a good tutorial for grub2. It was written in the ubuntu forms but is the same for Mint.Go to article "12 Reinstalling Grub2.

Grub2

After reading if you still have questions we will try and help.

Do not worry about Easy BCD, when reinstalling grub2 it will overwrite the MBR.

Larry after looking at this again, I don't think OP has problem, since wins bootloader is working & recognizing both os,

Can't OP remove wins entry from grub & bypass grub menu?
I believe that I saw it somewhere.

Wouldn't help.
The OP is (now) complaining that there is two bootloaders. Can't be avoided. Can be ameliorated to some extent (hiding menu, and/or short time-outs) but you still have to run through both lots of code sometime. Yes, you can remove entries from either (both) boot menus.

Hi @ all,

I have Vista installed on an Fake/Soft-RAID5 on a Intel(R) controller and a 1TB connect to an Marvell controller in AHCI mode.
The 1TB HDD have 4 Partitions:
500 GB Vista Backups (NTFS)
166 GB Linux-Shared (NTFS)
166 GB Linux-Ultimate-2.9 (Ext4)
166 GB Linux-Backup

For the first, no all actual Linux-OS's or Linux-Live-CD load the "dmraid"-driver.
So by Linux-Installation, the GRUB-Bootloader will be written on the RAID-Array.
Now if the Linux-Installation include the "dmraid"-driver you are luky cause of you can boot all OS's.
If not, the GRUB-Bootloader dont find neither Linux nor Windows.

Questions:
1) How can I set the Linux-Bootloader on the 1TB HDD?
2) What should I do (with Easy-BCD) in order to jump on 1TB-HDD and boot Linux?
3) The GRUB Boot-Meue show me only the Kernel-name, How can I let appair e.g. "Linux Ultimate 64 Bit"?
4) Due the big place on the HDD, I would try other Linux OS's, How can I distinguish between the different Linux if only the kernel-name is showed?

Thanks in advance and best regards.

Windows RE ISO: Windows 7 RE, Windows Vista RE.... It's free and you can download from Microsoft homepage, it take 107MB on the CD.
Microsoft give this Recovery Enviorement for repairing MS-OS also without installations-DVD.
