dual boot win7, mint 10.Reinstalled win7 now no OS will boot

Post by yeolde777 » Mon Feb 07, 2011 2:48 pm

hi,

Im quite new to linux, but here is my problem. I have had win7 on this laptop, downloaded linux mint 10 julia and made a partition about 220 gb linux mint and 400 gb win7 roughly. This been wokring flawless for months, I have the linux boot up menu at start up, and linux mint usually start if I dont go down on the list and choose win7 loader.

Today I decided to go into win 7 and run my recovery cds since its been running slow lately. I chose to wipe all c drive, the 400 gb one with win7. No problems, installed it, it booted up couple times with linux boot menu, the partitions and linux swap was still there. Then I go into windows, it downloads information and drivers and i set the time and network, then when Im asked to restart, and when I do.. my pc just start restarting over and over again with few seconds in between. No boot menu, just f2 for setup.. I then put in a linux mint 10 cd, and now im booted on the cd, and I am not in my personal linux mint desktop environment.

I have added a screenshot of the partitions.. hope someone can help me, im stuck !

cheers guys

Bernie

Hi!
Please first read my help.

Edit:
Run "findGrub" and post the output - I suppose you only see "no Grub"; in my help there is a suggestion what to do.

that made me bit unsure what part of it you refer to :) bit technical for me, could you specify? i cannot press c in boot menu, cause i dont get a boot menu, so neither linux or windows want to boot

edit, thanks ill try that

is it possible it has wiped my linux partition when i erased c drive with windows, cause it says linux is currently not installed, You can install it by typing:
sudo apt-get install user-mode-linux

Hi!
If you don't have to save important data you should consider to make a fresh installation, but before that creating partitions with GParted:
root (10 - 15 GB), home and maybe swap (size: 1.5 * RAM).

But I do not have as much time as usually.

You might need to reinstall grub. it is easily done from live cd. googling always offer the fastest help you can expect. see here: http://www.ubuntu-inside.me/2009/06/how ... ndows.html dont have much time, am in hurry rite now, sorry for such short reply tho.

Hi!
Please copy the following (I name it "findGrub") in a Terminal and post the output:

Code: Select all

sudo fdisk -l 2>/dev/null | egrep "Disk /|/dev/" | sed "s#^/dev/#Part /dev/#" | awk '{print $2}' | sed 's/://' | xargs -n1 -IX sudo sh -c "hexdump -v -s 0x80 -n  2 -e '2/1 \"%x\" \"\\n\"' X | xargs -n1 -IY sh -c \"case  \"Y\" in '48b4') echo X: GRUB 2 v1.96 ;; 'aa75' | '5272') echo X: GRUB Legacy ;; '7c3c') echo X: GRUB 2 v1.97 or higher ;; *) echo X: No GRUB Y ;; esac\""
Exactly that you will find in my help!

thanks for the reply guys, I appreciate it!. I had to wipe the whole disc and try reinstall with windows recovery, that didnt work, didnt find the boot.ini file apparently even tho i tried two times with the recovery cd's.. anyway, now i wiped all partions with partition wizard, then installed linux mint 10 on the whole disk, i attached a picture. Problem is now I cant resize the disc with gparted, because I wanna make a dual boot and install windows 7. Anyone know how I can easily make a partition and install the windows 7 on it? Even if I have to wipe out linux mint again, thats ok, cause I need to have a dual boot. Thanks for all the help so far!

Edit: forgot the pic first time, so here it is

Hi!
To avoid problems, you should delete and create partitions with GParted live latest (V 0.7), first install Windows and afterwards Mint:
Windows 2 primary partitions, maybe a primary swap or data exchange partition and an extended partition as a container for several Linux partitions - as e.g. root and home (and maybe swap, if you have created a data partition.)

You have a choice of using physical partitions or extended (logical partitions) for an OS: Linux or windows

Windows OS is safest to install first in the first primary partition: there can be up to 4 primary partitions on a hard drive, a legacy of dos partition schemes
--the first partitions in dos/windows parlance is the C:\ drive

If you only intend to have a few OS installed, there is no great advantage to not using the primary partitions available, and it makes it easier to keep them physically separate: you are working/using one partition at a time
  • Less change of accidentally wiping out an OS in an extended (logical) partition area, since that extended partition is part of another physical/primary partition: the primary one (of the 4 available)
An overview of partitions..
http://en.wikipedia.org/wiki/Disk_partitioning
--skip it period or skim for the definitions if you want (Primary, extended, logical)
