Lost Access To Windows 7 Drive (Dual-Boot Windows 7 & Ubuntu)
Aug 26, 2012
I lost access to my windows 7 drive (Dual-boot windows 7 & Ubuntu). every time I try to run Windows 7 I get the message: Bootmgr is compressed, Press CTRL_ALT-DEL to restart. I could run Bootrec /fixmbr or diskpart or attrib to rebuild my mbr table through DOS command window using my windows 7 recovery CD. The problem I cannot access drive C: where my windows 7 are. I get the error message: Cannot open volume for direct access or system cannot find the drive path or specified. I still can access all my windows folders and files through home folder in Ubuntu. I don't want to reformat and reinstall windows. Is there is a way to run the DOS commands within Ubuntu

I have a Toshiba laptop that came with a preinstalled copy of Windows-7 (64 bit) version purchased in July 2010. No setup disk came with the laptop, but there is a "Toshiba recovery media creator" utility. Now, I want to format my laptop, and here I have few queries regarding this:
[1] What is the better option for formatting my drive? Should I use the Toshiba media-creator or install a clean version of Windows-7 from an ISO download (am I allowed to do that? If so, what is a good site to download?) There is a "sticker-certificate" on the bottom of my laptop with a product-key. Will it work with the new install?
[2] Do I have the option of installing a 32-bit version of Windows-7 instead of 64-bit with the above license? The reason is that most applications I use are 32-bit and hence a 32-bit OS is better suited for me. But does the license allow me to do that?
[3] (The tricky part) - Since I have a good 320GB HDD, I want to dual-boot by creating two partitions - with a linux distribution (Ubuntu/openSuse) running on the second partition? Assuming I don't have the option of clean-install, will I be able to create the extra partition for linux using the Toshiba utility?

I installed Ubuntu on a older Toshiba laptop. When I boot up it asks me to select either Windows 7 or Ubuntu. I want to get rid of the Ubuntu disk partition and give that 2.9 GB space to my primary hard drive. I go into compmgmt.msc but I can't execute any commands on that disk partition.

I have set up a dual boot- Windows 7 pro & XP ultimate, both on separate SSD's, all OK. I also have two 3TB HDD's set up under windows 7 RAID, all OK. In XP under drive management the RAID drives show up twice, once as 775GB unused drives with no drive letter allocated and also as 2.7GB RAID drives with status 'failed', drives marked as 'missing'. Is there a way I can get the RAID drive accessible under XP?

I have a Windows 7 OS installed on a SATA drive, A few days ago I installed Ubuntu 10.10 on an IDE drive. So far the only way is to switch the HDD drives in BIOS to boot up the one I want.

I currently run Ubuntu as the sole OS on my Laptop. Using a G-Parted live CD I partitioned half of my disk space, the one half dedicated to running Ubuntu and the other half to Windows 7. I downloaded a torrent of Windows 7, one that I have used before with success (so one that I trust) and burned it to a DVD-RW at the slowest burning speed possible. I booted Windows 7 through the DVD and began to do a clean install of Windows 7 on this one Partition that I left completely empty for the new OS. Everything runs smoothly and I go through the set-up until suddenly the installation hangs at 0% when 'Expanding Windows Files'.

I can't get Win 7 to boot after setting up dual boot (Ubuntu 10.10) on my GF's laptop. I'll describe the problem and everything that has been tried so far. REALLY hoping somebody has an idea, I'm getting desperate.I installed Ubuntu last night via the Live CD. Used the Live version to install alongside Windows and partition the drive, install Grub, etc. At reboot, after POST it would just go to a black screen with a flashing cursor. I could only run off the live CD. A forum member determined the Grub was trying to load from the wrong partition. We changed that and voila! Grub now loads properly. I can boot into Ubunto via Grub with zero problems. HOWEVER: when I try to boot into Win 7 from Grub, it just locks at the same flashing cursor of death screen. The 7 partition is till intact, I can see and access all the files on the 7 partition from within Ubuntu, however 7 will not boot. I have tried downloading and burning the Win 7 repair disk and doing all of the following,Running the automatic Start Up Repair - several times. All it does is remove Grub, but booting still goes to the flashing cursor and I have to reinstall Grub again to be able to do anything after POST.I have used the command prompt to run "bootsect /nt60 SYS /mbr". Has the same effect as above.I have used all the bootsec.exe /fixmbr, /fixboot, and /rebuildBCD commands. Again, all have the same effect and I have to reinstall Grub to get anywhere.I don't have an installation disk to try and just do a repair install because Asus apparently doesn't feel that I would need one of these. All I have is the recovery disks from the Asus AIRecovery application that want to just re-format the entire drive and start over. This isn't an option. It's my GF's laptop (mine gave up the ghost last week) and we both have WAY too much highly important data on here. Not to mention she would castrate me . Now from all my research the only other thing I've come across that sounds possible is that the boot flag needs to be set to a different partition. Somebody had a somewhat similar problem and it turned out the way Dell set up the system the boot flag had to be moved to a recovery partition and it worked fine. I'm wondering if Asus has something similar going on, but I can't figure out how to move the boot flag. I'm going on 12 straight hours of working on this now

I just installed Ubuntu to make my computer dual boot with Windows 7. When the option in Ubuntu came up to install it along Windows 7, I selected it. Well, after the install my monitor pops up a box saying "Out of Range" and nothing comes up, then Ubuntu boots. I never get the option to boot Win7. If I hit a button while the monitor is out of range, nothing boots.

I had windows installed on a disk (sda) and decided to install ubuntu 10.10 in another disk (sdb). Ubuntu installed Grub2 boot loader in sdb and both systems seem to work fine. Except windows hibernation (which worked normally before the Ubuntu installation). What happens is this:
1. If I set the BIOS to startup from disk sdb, GRUB comes out. When I select windows and try to hibernate, the screen goes black and after a couple of seconds the log in screen appears. So, I can not hibernate windows when I use GRUB. By the way, ubuntu hibernates normally.
2. If I set the BIOS to startup from disk sda, windows load (without GRUB of course) and hibernate actually works. But when I turn on the pc windows resuming is the only option. I can not activate the bbs popup and even if I set bios to boot from the other disk (sdb) the system seems to ignore me and resumes windows without displaying GRUB loader.So, I can either hibernate windows but have to resume before I can use ubuntu or start windows using grub and not have the option to hibernate. From the above I get that windows 7 have a way of controlling the system's BIOS and prevent loading another os when windows are hibernated. I say windows 7 because my laptop has a similar dual boot (vista with ubuntu 9.04) and hibernation works for both systems and I can load whichever I want after that. I tried to find information about Windows 7 hibernation and bios but I couldn't find anything clear enough.
I have also tried EasyBCD but it didn't change a thing. I have already seen the posts about active partitions, boot partitions, boot flag (in ubuntu), turned off hybrid sleep, prevented all devices from waking up windows but nothing works. I started a thread ([ubuntu] Hibernate Problem in Windows 7 but not in Ubuntu 10.10 - Ubuntu Forums) since I though it was a GRUB2 problem but no one seemed to know what to do (or no one cared)... So, I' m left with the above assumption (windows 7 controlling bios).

I have Ubuntu dual booting on Windows 7. After the bios load, is there anyway that I can make Windows 7 boot right away without selecting anything on the OS selection? The same way it would boot without dual boot...if that makes any sense.If the above exists: Let's say I use Windows 7 all the time, but one day I decide to boot into Ubuntu. Is there a way that I can press a button, before Windows 7 loads, to make the OS selection come up?I tried to make myself as clear as possible and I hope that you understand what I'm trying to say.

I want to upgrade Vista to Windows 7, but without disturbing my Ubuntu installation, which is dual boot with Vista. I would prefer to do a clean install of Windows 7 over Vista, which has had niggling little issues (I resolve them and new ones appear) ever since I bought the pc. I don't have the recovery discs for Vista (the ones you make when you buy a new system) as they went missing during a major move.
What is the best way to accomplish all the above? Also, from what I understand, a clean installation can be done with an upgrade version of Windows 7 as long as a previous version of Vista or XP is already on the machine?

I set up a dual boot of Ubuntu and Windows 7 on my lenovo u330 laptop a couple months ago and everything was working fine. That was till I found a problem with the wireless when switching from Ubuntu over to 7. I found that if I left the wireless off in Ubuntu and restart to 7, the wireless is completely disconnected in 7. Later I learned that if I enabled the wireless in Ubuntu and restart into 7, the wireless works fine. Now, the major problem is that the Ubuntu 11.04 update completely screwed the Ubuntu installation. The graphics nor the internet worked after the update so basically I'm stuck with the wireless off in Windows 7.
Also, I deleted the Ubuntu partition to possibly reinstall it but another problem is that I got the install from a friend (who isn't around). Someone told me that Ubuntu actually shuts down the wireless card at the hardware level. Any low level way of enabling the wireless adapter in Windows 7? ipconfig gives me the "Media disconnected" message on all of the adapter connections. I have already tried reinstalling wireless drivers as well and none of the Windows 7 troubleshooting apps work whatsoever.

I am thinking about dual-booting my system with Windows 7 as the main OS, and linux ubuntu as a secondary. I have a few questions:
1. How much space should I leave for ubuntu's partition?
2. How do I make a swap partition (or whatever it is called, for swapping files between OS's)?
3. Can I set it up to automatically boot into windows unless I am holding down a specific key, or something similar?
BTW, my HDD is ~500gb, but my current (factory) windows partition is 450gb.

I've got a bit of a perplexing problem here that I hope somebody can provide some insight on. Set up the dual boot with your (very awesome) tutorial and everything works perfectly there. Windows 7 was installed first to the C: drive, XP is on an E: partition of the same drive. The D: drive is a second physical drive that is just used for file storage. If it matters, both physical drives are paired drives in Raid1.
The problem comes when I've loaded into Windows XP, I can't access the D: storage drive. It reads as size 0, and can't be formatted or read.
Under Windows 7, everything works. I can access the storage drive fine and have no problems using it.
I originally thought it was a permissions thing because the D: drive was formatted in Windows 7, but in XP I can read from the Windows 7 C: drive just fine.
I am at a loss, can anybody offer any suggestions as to why the drive would read fine under 7 but not when in XP?

I would like to install Linux Ubuntu on my laptop alongside Windows using dual boot. However, people keep telling me that it is not a good idea this to be done on a laptop because of driver comparability and stuff like that. So is it OK if dual boot Ubuntu and Windows on a laptop or it is a terrible idea?

I read that if you have Windows 7 installed, it ruins Ubuntu. I want my computer to have both, so I was wondering, how can I dual boot them without them clashing? I don't want to use Wubi, by the way.

I had Windows 7 and Xubuntu set up in dual boot by EasyBCD, a well known utility.Today the linux kernel has been updated and, after the following reboot, the choice of Xubuntu OS at the dual boot prompt didn't work.So I went through Windows, launched EasyBCD to fix things and:
- changed the order the entries (Win 7 up, first)
- selected Windows 7 as default OS
- removed Xubuntu entry
- added again Xubuntu entry through EasyBCD procedure
- saved (maybe I should have saved after each of the changes)
When I rebooted I've found that two identical Xubuntu entries, each pointing to the Linux OS, and no Win 7.I've tried to access Win 7 by Grub, but it points to the dual boot screen, so I'm at start point again.I don't have the Win 7 disk but the usual recovery partition. No backup. Going through the recovery partition gets me back to the dual boot screen..Is there any way to put it in order again? Could you suggestions work in this case?I know that, from Linux, I can install and overwrite MBR with free mbr.bin
sudo apt-get install syslinux
sudo dd if=/usr/lib/syslinux/mbr.bin of=/dev/sda
But I'm not sure it will give me back Windows 7.

I have messed up my dual boot of XP Pro and Seven
Seven was working well, but XP was playing up.
I did a restore from an earlier acronis image of XP.
XP now works again, but as you have guessed I have lost the dual boot menu to select Windows 7 when I bootup.
I know boot.ini does not apply with Seven.
Please tell me how to get my neatly tweaked Seven back on the boot menu,

Ok so I am running two operating systems at the moment: Windows 7 Ultimate 64x and Ubuntu Linux 9.10
I have them both in my dual boot menu, but I have a question as to how to organize them.
I recently visited this thread: Dual-Boot Windows 7 64-bit and 32-bit
...and they were basically explaining how to set your default boot OS to Windows 7. Well, I kinda have the same problem, except for when I follow the instructions on that thread, I get to the part where it tells you how to set it to default, but the only OS that shows up is Windows 7. It does not show any sign of Ubuntu whatsoever. Is it because I have to have a WINDOWS OS or what? But I would like to organize my boot menu to where it highlights Windows 7 as the first boot option rather than Ubuntu because I want Windows 7 to be the first OS on the list. Any help on how to make that happen, if possible?

I have Windows 7 RC1 installed for some time, dual-booting with Windows XP. And that worked like a charm. But a couple of days ago I installed Ubuntu on the Windows XP partition (after formatting it with ext3, of course). But the thing is, I have been trying to boot into my dear Windows 7 ever since, with no success.
It didn't show in the boot manager, so I changed the menu.lst in Ubuntu. Thus it can be seen, but to no avail, as it does not work. I have tryed fixing it with the Windows 7 installation DVD, but it did not work. And I really ran out of ideas; also I would like to keep both my OS-es as they are (all data), if that's possible somehow.

Ok so I have Windows 7 and Ubuntu desktop installed on my HDD. I used gparted and deleted my ubuntu partition and set it NTFS. But I forgot about the GRUB loader. Now when I boot up, I get the "error 22".
Anyways, how do I set it so I can just boot Windows 7?
Also! I'm on a netbook so it has to be a USB method.

I have a small query about this whole partitioning business. I'm trying to set up a partition so I can dual-boot Windows 7 and Ubuntu.
My computer came with a Dell Recovery partition and an OEM partition as well as the main C: drive, which are all primaries. I've created a new logical drive, which I've called Z:, with the idea being to install the Linux OS in that chunk of the drive.
My first question: First up, I've formatted it as "exFAT" - is this the same as FAT32?
Next question: can I divide this 'Z' into smaller chunks with different formats, or do they all have to be the same format? I was hoping to be able to format a small bit of the drive into a Linux file-system so that both OSs can be kept entirely separate from each other, but leave the bulk of it as FAT so that I can see my files with both OSs. If this is not possible, what would be the best way to achieve the desired result?

The problem I'm having is that I had been running WinXP SP3, I used GParted to partition my hdd so I could do a clean install and try out windows 7. The odd thing is though, at first when it would boot up I'd have two option to select from, either "Windows 7" or "Select an older version of windows", then I reinstalled windows 7 at one point(to the same partition used before) and lost that menu all together, now whenever I turn my PC on it just acts like windows 7 is the only OS installed.
I know my other partition is still there though, my question is, how would I go about retrieving it if possible. Can I just pop in my WinXP disc and do a repair or recovery on the other partition? Never had this problem dual booting windows and linux so im unsure as to what I should do.

Can I do what I want without screwing up my xp installation?
