General :: Win7 And Dual Ubuntu 9.10 Partitions ?
Mar 26, 2010
I have a Windows Vista box upgraded to Win7 and then installed two (yes two) instances of Ubuntu 9.10 on the same box.
I don't need one of them (it had a corrupted install ISO disk) and want to remove the partition using fdisk or parted or similar utility.
How do I know which instance of Ubuntu is used for each partition I selected when I reboot the box?
There are two different versions displayed and I always select the newer one but how do I know if I remove the right one or not?
Also, when I restart in Win7, the BIOS/OS wants to check the disk everytime and now I've started skipping this check (it takes several mins).

I have been an MCSA for the last 20 years, but recently I have been very impressed indeed with Ubuntu 11.04, having dabbled with and then discarded Susi Linux some five years ago. My problem may be summarised as outlined below: Using the downloadable ISO I installed Ubuntu 11.04 as a dual boot on a Win7 100GB HDD on my Lenovo T61 laptop. No problem they both rock and I'm very impressed. During the installation procedure I selected the largest partition sizes available from the Ubuntu installer wizard being 25GB Extended split into 18GB Ext4, and 3.2GB and 3.2 GB swaps (I couldn't suss out any way of manually increasing them any further).
I found that the 11.04 Startup Manager application didn't work at all, so I downloaded and installed Grub Customizer 2.1..and that did work after a fashion.. certainly enough to actually effect changes in the grub configuration settings. Everything worked so well on the 100GB HDD that I decided to transpose the entire disk image to a new 500GB WD Scorpio and make the dual boot my main working disk. Using Acronis I imaged off the 100GB installation selecting the partition by partition, and retain disk signature options. I then recovered the image to the new 500GB HDD and everything works beautifully on the new HDD.
Except of course all the partitions are still the same size. I won't waste your reading time recounting everything that I have done using Acronis Disk Director (V Good) and Gparted (not so good), but needless to say whatever I do Grub won't have it, and I have lost count of the times that I have re-recovered the good image. Basically I want to increase the partion sizes to apportion larger partitions to both Win 7 and 11.04 and obviously I'm missing something somewhere.
Fdisk -l -u produces..
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x9f011ed1 .....

I'm completely new to Ubuntu, and haven't actually installed it yet, so my questions aren't concerned about how I use it, but rather the problems of installment and more importantly how to get started. The first thing I got a little question for is how to split my HDD into two partitions in order to install Ubuntu, as I will be dual-booting it with Windows 7. The second thing I want to ask about is how big the risk of corrupting my HDD is when installing Ubuntu, and whether I can take some precautions in order to reduce the risk of said thing. The third thing I'm gonna ask about is how to get drivers for my graphics and that alike. And fourth and last: Is it going to make a difference that I'm running it on a laptop?

I'm only a few months into working with Linux, and am getting used to it slowly. I messed up trying to load Ubuntu 10.04 on a new Gateway (Acer) laptop that has Win7 on it. I need Windoze for a couple commercial applications. Neither will boot w/o a CD. I'm guessing I messed up the load. I would like directions/ideas. I think that since Windoze is such a hog, I should remove Linux and partitions, restore Win7 and try again. Do I need to do something to GRUB as well?

I have a e-machine x64 machine, running win 7 home premium. I have tried to run WUBI, and do a side by side install, but either way, I cannot get it to dual-boot. Any ideas? Comments (other than trashing Win-7?).

Current rig:
Toshiba Satellite L455 laptop
Celeron 2.20 GHz
Windows 7, 64bit
3GB RAM
I downloaded the DVD release of Kubuntu 10.04, from Kubuntu.org. The file is: Kubuntu-10.04-dvd-amd64.rar . I burned it to a DVD, as image, with ImgBurn application. See any problems so far? I want to dual-boot, leaving my Win7 in tact. I am confident that I can handle this with some patient instruction.

I need to install linux (with Grub) un a disk with windows 7 loader (i have 2x choice on that loader and i need to use it).
I tried to dig to find out some methods but nothing.
It's safe? It's better to install Grub on another partition - same physical disk?

I would like to know the best way to dual boot an already installed Win7 HDD, with adding a second HDD to which I will install Mint9?
I have attempted this in the past with Mint8, but managed to screw it up some how with Mint 8`s Beta Grub2! So bear with me if I am skittish on repeating a "conventional" Grub bootloader selection approach!
This time I would prefer to install Mint9 to it`s own HDD with Win7 disconnected if possible, and installing Mint`s Grub bootloader directly to the Mint HDD installation, just to insure Win7s MBR isn't affected by the Mint9 installation, by keeping each O.S. and it`s bootloader completely separate and apart. Of course then comes the question of how to access my new Mint 9 installation, since reconnecting my Win7 HDD (with it`s MBR) will become the default, with no knowledge of any Mint installation.
Would a third party bootloader such as "Easy BCD" be the way to go? Or am I over complicating what I would like to accomplish here? The main thing is: NOT having to upset my twice installed Win7 installation again!

I have a win7/10.10 dual-boot set up, more or less following the lifehacker.com tutorial (I know, I know). I had to reinstall windows, and its taken over the MBR so that only win7 boots now. My shared drive and the ubuntu filesystem are still there, I just can't get to them without a boot cd. So, I tried to follow the tutorials, which all basically say to reinstall grub or grub2. I tried one method, but ubuntu told me that installing grub2 anywhere but the MBR was a bad idea

I just tried to install OpenSUSE 11.3 on sda4 which is approximately the 2nd half of a 1TB drive, with a pre-existing Win7 installation on the 1st half. The installation summary (before it made any changes) told me "The bootloader is installed on a partition that does not lie entirely below 128GB. The system might not boot." Naturally, not keen on having a computer that won't boot, I aborted the installation.
Of course it's not below 128GB -- Windows is there.
Is there a workaround that is straightforward enough for someone who has very limited experience with GNU/Linux and isn't a comp-sci student?

I'm a pretty experienced Windows user, and have coded in x86 and win32 API for a while, so I know the system reasonably well. I've used windows since the days of Win95, and prior to that I had an Amiga - so I'm pretty rusty in unix-like operating systems. I have little C coding knowledge beyond reading it, though I can understand what the programmer is doing from reading the source. My only experience with installing linux was on a 486 laptop that failed spectacularly when the CDROM couldn't be detected and used, so I'm necessarily a little wary of doing this, but I've become quite exasperated with Windows lately.
I have decided to make my life interesting (if not easier at first) by dual-booting Linux with Win7. My current machine is a dual-core intel laptop with 2GB of RAM and an ATI X1250 mobile GPU, with a 120GB HDD. I have two partitions currently on this machine - both 60GB-ish. The main C: drive is Win7. I'm aware of the hidden partition that Windows installs. I have an external 1TB USB drive for my applications and data, so space shouldn't be a problem. There is no floppy drive (unsurprisingly) and I can boot from the internal DVD drive.
I have chosen the Slackware 13 distro because it seems to be well respected as a learning tool for unix-like operating systems. My main aim here is not to abandon Windows at first, but to learn a new OS. I'm aware that Slack may not be the most user-friendly distro, but will give me knowledge that I might not gain under other distros. If I'm making a mistake here, then let me know! I have plenty of free time to devote to this little project, and I'm not afraid to learn. I am however afraid to destroy my Win7 fall-back. If all else fails, I need to be able to go back to a working OS to jump on the net to find the answer to what went wrong.
So my question, as per the subject title, is: What do I need to know before I do this? I have no idea what I'm doing with regard disk partitioning beyond Partition Magic - which I don't actually possess anymore. I can use the Windows disk management app. I have no idea how to manage a boot sector. So are there any gotchas that I need to bear in mind? I've already read this thread: [URL]. Which I must admit looks very complicated! I have a fair bit of time before my Slackware 13 DVD-ISO image downloads (20KB/Sec) so have some time to gather information.

I had Windows Vista Business in my compaq presario CQ40-145 TU laptop, over which I installed Fedora 13, making the system dual boot. The Windows is set to be the default OS. Now I want to replace Vista with Windows 7 professional without affecting Fedora. As far as I understand, during boot up, the system enters Fedora's booting process and then gets redirected to Windows, and it is not directly windows even if the default OS is windows.
The reason behind not disturbing fedora is the updates, extra software and packages installed and the pain and time it took me to make my speakers, wlan and flash player work in it. I even don't remember the exact process of what I did. I don't have now so much time to search for it again. So I will take up only that way in which Fedora is not affected at all. And the second problem is my DVD drive is not working at all. So I'll like using USB stick for the same.

I would like to triple partition for win7, ubuntu, and all other files-data, music, etc. And I understand this can be easily be done via the disk management feature. Obviously a 2TB HD is huge for me and I probably will never come close to filling it. I will eventually copy all my files from my old pc, but that totals about only 10GB.
My issue is what should be the actual size of the win7 and the ubuntu partitions? How many GB for win7 and how many GB for ubuntu?

I have a Centos 5.5 system that had 2 primary partitions (2nd is setup as LVM with multiple LVM partitions) and then installed Windows 7 as Dual Boot.
However, Windows 7 has installed a 200MB system partition which is GPT/EFI as partition 3 and the Win7 OS as a Primary Partition.
I have a heap of space undefined after this fourth primary partition.
However, as 4 primary partitions have been used, I can no longer create an extended partition to utilise this.
As such I would like to know what is the best and safest way to proceed, and if possible step by steps instructions for the best option eg:
1. Delete the Windows 7 System Partition and create the extended partition (I expect this will prevent Windows from booting)
2. Use something like partition magic to change the Win 7 OS Partition 4 to an extended partition (Not sure if this will work)
3. Make changes to the overall system including both Linux and Windows so that it will use GPT only (I have
had no experience with GPT so this is a bit scary)
4. Other?

I have 1 HD with the following OSes, each on his own partition:
p1 WinXP
p2 Win7
p3 Ubuntu
p4 Ubuntu Studio
p5 Unallocated (not actually a partition)
I intended to create a 5th partition, formatted as NTFS, for data. That's when I found out that Windows only supports 4 partitions per disk (yeah, I know, should've looked it up first). On Win7 Disk Management applet, they're all listed as "Primary Partition".
I've come up with a few possible solutions: s1. Move partitions p3 & p4 down towards the end of the HD, and add half of the available space to partition p2 (Win7) and the other half to partition p4 (Ubuntu Studio).
s2. Move partitions p3 & p4 to the end of the HD, and add all available space to partition p2 (Win7).
s3. Increase partition p4 (Ubuntu Studio) to take up all the available space.
My questions:
q1. Win7 Disk Management applet gives me no option to move or resize (other than shrink) the partitions. Does this mean I'll have to use another partition manager (e.g., gparted)?
q2. If I move the partitions p3 & p4 (both Ubuntu), will there be any impact on grub?
q3. Is there any way to turn partition p4 to extended instead of primary? If so, what are the consequences?

i installed win7 ultimate on a 2TB HD and was hoping to dual-boot it with meerkat, i did a standard install and shrunk the partition using win7 disk management to leave 500GB for ubuntu.problem is ubuntu can't detect the existing win7 install, when selecting advanced setup it just shows one big unallocated partition.
i went back into win7 and extended the partition again, then booted into ubuntu live cd to see if maybe gparted would do the trick. gparted also cannot detect the existing win7 install and just displays unallocated 1.82TB.in terminal if i do 'sudo parted /dev/sda print' i get this message:
Warning: /dev/sda contains GPT signatures, indicating that it has a GPT table.However, it does not have a valid fake msdos partition table, as it should.Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Is this a GPT partition table? Yes/No? ^C

I've resized partitions with some program - perhaps even gparted - but from Win7. partitions are indeed resized, but now I can't boot Win7, grub says:
"No such device found - No such partition found".
I tried to use some advices on similar problems I found here (like adding GRUB_PRELOAD_MODULES="part_msdos" to etc/default/grub and running grub-mkconfig after), but nothing helped. I guess I could restore win7 with installation dvd but I want to fix GRUB (and have both ubuntu 10.10 and win7)

I have a dual boot Acer Aspire One, after reinstalling Windows back to "original factory", the way it was straight out of the box, it now will not boot up at all. It goes to the Windows start screen goes blank, and loops there infinitely. Is there a USB tool I can use to figure out what went wrong and recover either my Windows or Linux partition with out having to do a complete reinstall?

I'm trying to dual boot F14 along side of Win7 and I'm running into partitioning errors - "Could not allocate requested partitions: not enough free space on disks" I used the Win7 Disk Management to shrink the C: drive by 100G, and the Disk Utility in F14 shows the unallocated space. Here is what the current layout looks like:
--210Mb bootable (sda1)
--168Gb (sda2) --Win7
--105Gb unallocated -- Future home to F14
--31Gb extended (sda 3) -- not sure what this is used for
--31Gb (sda 5) -- Lenovo drivers
--16Gb (sda 4) -- Lenovo restore
Am I running into the partition limit I have been reading about? If so, is there a way to get around this? I really don't want to delete the partitions yet.

My wife wants Ubuntu dual booted on her new Acer laptop which has Windows 7. My question: Is 10.10 stable enough to put on her computer? We have used Ubuntu for a number of years and have always stayed current with upgrades, but I have become leery lately of rushing into new versions of Ubuntu. I had too many problems when I upgraded to the last couple of times. I'm inclined to put 10.04 on her computer unless I can be assured that 10.10 is good to go. Or would I be well-advised to move back a version or two?

I bought a new computer (laptop HP DV6-1375dx) and I want to set a dual boot with win7, like I did with my desktop (clean install) However, my question is, with the new laptop all I have is the rescue disks vs. having the single OEM version. IS that a problem? for the desktop I followed lifehackers article "Dual boot win7 and ubuntu in perfect harmony." no problems at all.
what I am afraid of is formatting the new hard drive and the recovery partition and not being able to use the disks for some reason....am I over-reacting?

Until very recently I was running Ubuntu 9.10 (Karmic Koala) installed on a 20 GB hard disk and Windows XP (SP3) installed on RAID 1 array of 2 x 250 GB disks, very happily along side each other and using GRUB as the bootloader installed on the smaller 20 GB drive.
I have decided to upgrade to Windows 7, and was struggling with the installation failing with the seemingly quite common "Setup was unable to create a new system partition or locate and existing partition" error. Google seaching suggested unplugging my Ubuntu drive and then installing Win 7. This worked fine with the Ubuntu drive unplugged, however with the 20 GB plugged back in I can boot to GRUB, but it still has XP in the menu, and no option for Win 7.
I think I could get around the issue by re-installing Ubuntu, which would place GRUB on the MBR which is now on the 250 GB RAID 1 array, but I would rather have the system as it was before with GRUB and Ubuntu on the 20 GB drive.
I know I need to edit GRUB to remove the XP entry from the menu, but I have no idea how I would get Win 7 into GRUB, and what to do about the MBR which Win 7 put onto the RAID 1 array.
