hello all!

I had Windows 7, then I installed Linux Mint last version

I couldnt switch between 2 OS or didnt see Linux when boot

so i searched and found Boot Disk Repair on Ubuntu forums

installed on flash usb, chose recommended settings, and nothing changed

so I selected for advanced mode - and after that I have this error - Missin operating system


after that I tried to install Linux Mint again, chose previous partition and in the end error - cant install GRUB on that sda.. I chose partition for Windows and still cant instal..

any ideas how to fix boot error?

Im new to Linux.. and sry for Mistakes!


I appreciate ur help!


What should I do now?

id like to recover Windows 7 and swithc with Mint whn boot

Go here follow the instructions and post the results. http://bootinfoscript.sourceforge.net

Did you save the log from the boot repair ?. If so post that as well as the RESULTS.txt from bootinfoscript.

repair boot disk

http://paste.ubuntu.com/6950395/

so how bad situation is now?


I couldnt do bootinfoscript, I did as everything was described
I can do again and paste from Terminal, is it okay?


I could log into Windows 7 using LiveCD - PLOP boot manager, looks like good prog and I should look into it deeper

anyone please?

You have windows installed to the master boot record. You boot it (if you can) and download and install EasyBCD from the neosmart site. Read the instructions how to create an entry for Linux.

You could install Grub2 onto the master boot record and then reboot to Mint and if it works, run: sudo update-grub.
The link below explains some methods. Boot the Mint Live CD/flash drive (whatever you used to install Mint) and use the method 'via the LiveCD terminal. You have a separate boot partition on sda3 so use the method listed for installing to a boot partition.

okay...

I have 500mb Linux partition sda3 (that I suppose to be for boot partition) and another 33GB Linux partition sda4

I tried to mount first one - got an error

mount: mount point mnt/boot does not exist

repeated the same with this sda4 - still error

wrong command or wrong partition? I dont have any other Linux partitions except swap


anyone can help please?

sorry for slow answering

then tried this - sudo mount dev/sda3 /mnt

error - special device dev/sda3 does not exist.



Im running under Boot repair disk


is there any difference? I can try any other Live CD like Fedora, Mint, Ubuntu or it will be the same?

what is the output of when running boot repair disk

That would indicate that you did not first create the mount point from the Mint CD: sudo mkdir /mnt/boot
Repeat for the / filesystem directory: sudo mkdir /mnt/mint

Then run the mount command to those mount points: sudo mount -t ext4 /dev/sda3 /mnt/boot
Same for the / filesystem partition. The default filesystem for current Mint should be ext4 unless you changed that. After doing this, you should finish the process explained at the link I posted which I believe had this info.

fdisk -l output :



now will try to do what was written below

does it make difference?
