    Default A Simple Partition Fix..........Hopefully!

    Hey all,

    Kinda scratching my head at something and would love to sort this mess out. I've done quite a bit of searching here and there (as you'll see below) but still stumped...maybe something 'just went wrong'

    So here we go..

    Wanted to get back into Backtrack last night and seen there's a wonderful v5 (I used to use BT3). It was around 2am and didn't have any DVDS so I did the following.

    Created a 10gb partition via Windows and looked around for some software to maybe try help me boot into the ISO that way. I found EASYBCD and something else but in the end it just wouldn't boot into problem I thought, I'll wait until the next morning.

    Morning comes and I buy some RW DVDS. Burn the ISO and hey presto, we're good. Got a dual boot working. Checked both W7 and BT5 and they're working fine. So I go back to W7 and delete that old 10gb partition as I won't be needing, right?

    All hell breaks loose!

    Rebooting I get to a 'grub rescue' screen where I'm totally lost and no commands seem to work (help doesn't work?). I put the BT5 cd in, start fdisk and try to delete the 2 BT5 partitions - my logic here is to delete everything but W7 and just start over.

    I can't fix it that way, fdisk won't let me delete the partitions for some reason and I can't figure out a fix. I tried my W7 (Samsung laptop) recovery cd to maybe fix the boot record but it seems to fire back to the damn grub rescue command prompt..thing.

    I also noticed when booting into the recovery cd it's showing my W7 drive as E: now and not C:..?

    So I think of another idea...install BT5 again and hopefully it'll fix it.

    Seems to work...I'm sitting here now with W7, BT5a and BT5b; they all appear on the grub menu.

    Firstly - why on earth did deleting that 10gb partition cause so much havoc? Did I do something really stupid? My logic was that seeing as it was an NTFS partition and had nothing to do with BT5 (it only had that iso on it, remember) shouldn't of screwed it up? I must be missing something fundamental here. I can feel some of you facepalming, haha..

    Secondly - What's the safest way to delete one of the BT5 installs and tidy up my partitions? Shall I use gparted? I just don't want to end up at that grub rescue prompt again.

    Yeah..bit of a head scratcher.

    Thanks to all replies in advance. ))

    please post HDD map:
    1. Boot with liveDVD (any debian-based linux distro, I recommend Ubutu with 3.2 kernel like 10.10 version or later)..If you are using BT5 64bits, use an Ubuntu 64bits, if 32 bit BT5, use ubuntu 32Bit distro...So far so good.
    2. once booted, open up a terminal and type: fdisk -l and post uotput.
    3. Get rid of easyBCD and any fancy, pretty, look-amazing, little windows-based app that swear to work with linux.
    It seems to me like you installed grub in partition where ISO was downloaded or easyBCD did something with 10Gb partition before..Now you might want to recover grub which is something very easy, as fast as 2 commands..But before continuing, please post map of partitions.

    Sure thing. Thanks for helping out here.

    here's what fdisk -l gives me.

    Disk /dev/sda: 750.2 GB, 750156374016 bytes
    255 heads, 63 sectors/track, 91201 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Sector size (logical/physical): 512 bytes / 4096 bytes
    I/O size (minimum/optimal): 4096 bytes / 4096 bytes
    Disk identifier: 0xd3653c2f

    Device Boot Start End Blocks Id System
    /dev/sda1 * 1 13 102400 7 HPFS/NTFS
    Partition 1 does not end on cylinder boundary.
    /dev/sda2 13 20881 167617117+ 7 HPFS/NTFS
    /dev/sda3 20881 86864 530013185 f W95 Ext'd (LBA)
    Partition 3 does not start on physical sector boundary.
    /dev/sda4 88139 91202 24599552 27 Unknown
    Partition 4 does not end on cylinder boundary.
    /dev/sda5 35390 50820 123940994 7 HPFS/NTFS
    /dev/sda6 62835 85885 185145344 83 Linux
    /dev/sda7 85885 86864 7867392 82 Linux swap / Solaris
    /dev/sda8 20881 34795 111768576 83 Linux
    /dev/sda9 34795 35390 4771840 82 Linux swap / Solaris

    Just FYI there's a Samsung recovery partition there which is sda4 and I believe sda1 is the boot for w7. sda2 is my c:\ drive and sda5 is my other hard-drive. This leaves sda6 and sda7 (the first install of BT5) and sda8/sda9.

    I'm guessing we'll be working with sda8 and sda9.

    Using fdisk or gparted, can you confirm I'm good to delete sda8/sda9 and then merge this free space into the used partitions? I'm just nervous after this last mess up...really don't want to be seeing that grub rescue screen again lol.

    I'm alright with using fdisk but would prefer to do this sort've job with gparted as it has a gui which is a bit nicer to use hah.. is that alright to do?

    Edit: I've just opened up gparted within the first install of BT5 and all of the partitions apart from sda8/sda9 are unlocked? sda8/sda9 have a gold lock next to them? Not sure if that's important or not, just thought I'd let you know. I would've thought sda6 and sda7 would have the lock next to them as I'm using them right now...?

    Edit: It must be that I'm using the newer of the 2 installs when using gparted, ignore!
