Ubuntu :: Dual Boot With Win7 - Can't Load - "read Error"
Jun 30, 2011
I have an older pc now dedicated to ubuntu and run 11.04 32-bit no problem, and previous versions as well. I just got new hardware and assembled it and wanted to make it dual boot with win7. Found the information and got it working so I thought. Everything was peaches and cream until the install finished. A long long message appeared with read errors from some drive (i think it was my swap partition but its just a guess), appearing and disappearing to fast to read, so it don't know what it was trying to tell me aside from "read error". After the the message it said remove media and restart now. Which I did, booted to windows, modified the BSD to boot to Ubuntu or windows, Get the grub2 loader and select ubuntu. This is when everything goes awry, I dont get any loading screen just a singular purple screen, if I press any key, it starts to flash, and every subsequent key I press cause it to flash faster.
I can run the livecd (64-bit 11.04) no problems, As well as win7-64 (currently to post this message). But i cant get Ubuntu to load. I deleted and reformatted the partitions I'm using and reinstalled with the same problem.(/boot,swap,/(root) and /home) under windows management they are listed as healthy(ext4 -- except for swap,primary -- except for swap as logical and all set to beginning). So I guess the question is what could be cause this problem? My settings for install, my bios, or something else? My system specs are Asus mobo, amd phenom2 hexcore, 4gigs ram, 2 ati radeon crossfired, a 2 tb hd and a 40 gig ssd.

I have a problem trying to install CentOS 5 as a dual-boot with my Windows 7. Using Windows tools, I shrunk my main partition and created about a 100GB of unallocated free space. Then, I restarted my computer, booting from the CentOS dvd, but when choosing "Use free space on selected drives and create default layout" option during installation, I get an error saying that partitions couldn't be allocated as primary partitions and that there is not enough space left to create partition for /boot.

I managed somehow to successfully install a dual boot with Ubuntu 9.02 and Windows XP. Ubuntu was on a PATA drive and the WinXP was on a SATA drive. The SATA drive was configured to boot first. As I was having problems with Ubuntu I booted into WinXP, re-formatted the PATA drive, then restarted the computer and installed Ubuntu 9.10. It all went well.I rebooted the machine and the following message was on the screen:
GRUB Loading stage1.5.GRUB Loading, please wait....Error 17
I rebooted, changed the boot order so that the PATA disk (Ubuntu) started first, then the SATA(WinXP). Ubuntu loaded up the dual boot screen.I chose WINXP, but I was greeted with a black screen.I rebooted again and chose to load Ubuntu, which it did without a hitch.what I should do to restore my access to WinXP? Or should I start again? If so, how?

I have searched and read threads about the Bitlocker, grub and TPM issues that might show up, but I can't draw any conclusions as some information contradict each other. To make sure I don't screw up my pc as thought I need to make a new post.
At work I'm supposed to run Windows 7 and encrypt the win-partition with Bitlocker. I have installed Windows, turned on the encryption and it ties into the TPM. But as I am moving over to the *nix department I want to run Ubuntu as dual boot to check everything rusn fine with all the systems I need. Before I installed Windows I partioned the disk:
1,5 GB for system/bitlocker requirement
147 GB for Windows, C:
85 GB which is empty where I intend to install Ubuntu (not formated yet)
I boot into Windows with my bitlocker/TPM key on an USB-stick. Without the usb-stick the pc won't boot. Now, before I try to install Ubuntu I want to make sure to do it the right so I don't mess up the Windows installation or won't be able to boot the pc at all.
There seem to be several "schools" to this. Some suggest I should have installed Ubuntu first, then Windows and then encrypt. Some say, no worries just fire away and install since you are not planning to read the windows-partition from Ubuntu. Or an alternative, install but make sure to deactive the encryption during installation. Some say, install but make sure grub is installed in (multiple choices) location.

So we install Windows 7 home premium. Then in goes the Ubuntu Disk. Ubuntu seems to think that the windows 7 partition is one big lump of unallocated space. Tried multiple re-installs of Windows 7, all concluding the same. A bit of googling told me that it has something to do with partition tables or something. I even tried to use Gdisk to delete Gpt from the windows disk, which - as I have absolutely no idea what any of it means, - resulted in me screwing up the entire Win7 partition hence win7 not being able to boot anymore.
i've seen on the internet include a lot of technical garble which I don't understand. I've been using Linux for a while, but as far as partitioning and dual booting is concerned, it's always gone smoothly for me up until now

I have the option of selecting between win7 and Ubuntu during start up, but when i select Ubuntu it goes to the first 2 lines of command and then restarts again. Windows 7 works fine. This is the second installation of ubuntu on this computer, the first attempt did the same thing (would not boot into ubuntu but win was fine) after i lost power. This time i shut the computer off for a full week while i was on vacation. I have switched between windows and ubuntu a couple of times and had no issue with this installation.

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 turn back to openSUSE and install it in my machine (win7 installed first),but i can't boot from win7. openSUSE doesn't boot from win7 (like ubuntu) and i can't see ntfs win7 partition from openSUSE. Why openSUSE is so complicated about dual booting

I'm trying to dual-boot Windows 7 with openSuSE 11.4, i was told that i should install SuSE after windows 7 as it takes care of the boot-loader and automatically detects my windows installation and not vice-versa,
But that is not true in my case.
So i had 2 hard disks one had windows 7 installed and one was empty so i decided that i should get openSuSE 11.4 on the empty hard disk and dual-boot it with windows 7 (that i already had installed). Downloaded the DVD, put it on a USB and installed SuSE on the other hard disk normally, it detected my windows installation on my main hard disk but i didn't touch that, only formatted my other hard disk to ext4
After the installation it booted automatically into SuSE, but now every time on a fresh restart the system boots automatically into windows. Methods i have already tried to resolve this and it didn't work:
1. Booted from the DVD and selected an "Upgrade" not "New Installation" so i could boot again into my SuSE installation which did work, checked my "Boot Loader" options from YaST and checked the "Boot from MBR" option instead of the "Boot from root partition" option, That Did NOT work.
2. Used the same method to Boot into SuSE with the "Upgrade" Option opened up the terminal and tried to install grub manually again using this link

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?

There was windows 7 Home Basic pre installed onto Hcl Desktop at my Office, then I installed ubuntu 10.04 to it, everything was ok untill I restarted. When I select windows 7 from dual boot, it takes me back to dual boot grub page. So I did inserted Windows 7 cd and restored windows by this
Code:
bootrec.exe /fixboot
Now only windows 7 is working and booting. I want ubuntu 10.04 on the dual boot, how and what is exact method of recovering ubuntu without harming windows 7? Is it with ubuntu 10/04 cd?? If i do live cd and restore grub, will windows 7 work?? I haven't given any details of hd0 and root, i'll manage, just tell the procedure.

Should I first partition my HDD using partitioning software (Gparted ETC.)? I have Win7 as my primary but I just want some sort of linux OS on my laptop. I only want to give it 30GB, and I checked the partitioning helper that ubuntu 10.10 has on its installer and quite frankly, it sucks.

I've tried this a couple of times and can't load Ubuntu.Here's the scenerio, I have 3 partitions.
/dev/sda1 = ntfs (Win7)
/dev/sda2 = ext4 with the / mount point
/dev/sda3 = swap space
I've some tutorials where I need a /boot partition as well and others where I just need the root partition. At the bottom, there is a drop down box for you to select the device for boot loader installation. Those options include /dev/sda, /dev/sda1 (Win7) and /dev/sda2.
I need to do to get the dual boot working? My first thought is to install the boot loader onto /dev/sda but I'm unsure. It keeps booting Win7 and can't get the option to load Ubuntu.

I have installed the ubuntu 9.10 and the pc already have 2 win 7 OS and 1 win xp I installed the ubuntu from win xp every thing go just fine but in win 7 boat loader it detects the 2 win 7 OS , previous windows ( the xp )and the ubuntu which fails to load from win7 boot loader ( the first problem ) but it is present also in win xp boat loader so when choosing older windows the win xp bootloader let me choose between windows xp and ubuntu which works fine when choosing it the ubuntu bootloader appears with ubuntuubuntu safe modewin7 bootloader
the second problems that choosing win 7 after restarting the pc from ubuntu fail to open it begin loading with the windows logo and then just shutdown the whole pc as if i have unplugged it! the only way to let it open is to choose older windows>>> ubuntu >>>> ubuntu bootloader >>> where there is win 7 bootloader option it returns me again to win 7 bootloader but this time the windows load complete ( mostly but may shut down also!)

I install Fedora 14 32bits the same way I install Ubuntu. First, make unallocated space for it (about 150Gb). During the installation setup, I select "use all continuous free pace" as partition option, coz it's fastest and easiest. /dev/sda/ is selected as location for boot loader, and leaves Fedora as default boot target. Installation process goes very smoothly, but when the system restarts. The computer boots up as if Fedora has never been installed, it goes straight to Windows7, No GRUB boot loader menu whatsoever.
troubleshooting attempt #1: at first I thought it maybe the GRUB compatibility issue between 32bits Fedora and 64bits Win7. So I tried out 64bits Fedora, doesn't work.troubleshooting attempt #2: then I tried to install the boot loader on the Linux partition (first boot sector of boot partition) and let Windows 7 controls the startup menu by using FreeBCD.

Does ANYONE have a stable dual boot Win7 & Ubuntu 10.04 system? I have been trying for WEEKS to get a computer configured for my student lab. I get things going and everything seems to work for a few days. And then for no reason, the next time I reboot, Grub just seems to commit suicide.
Latest example. Win 7 & Ubuntu have been co-existing perfectly fine for about a week. Iow, I do something, then reboot, and the grub menu comes up - I select something and it boots my OS of choice for that session.
But today, I've been putting the last few touches on this computer before I use Clonezilla to copy it to all of the computers in the lab. You know - hard stuff like:
* set the default profile in Windows
* install a printer in both Ubuntu & Windows
* set a background image for the logon screens that have our "don't do anything bad" policy.
how there is nothing in there that should mess w/ grub or the boot loader, right? Yet I reboot the computer, I get to where grub should load - and BARF - I get the Bios splash screen again and the computer reboots on it's own. What the !@(#$&!@#$% is going on that this keeps happening to begin with?

I am relatively new to Ubuntu ; I started 6 months ago with 9.10 and it worked fine. Recently I bought from Ubuntu the 10.04 version in French. The installation (dual boot with W7) went well, I personalized the software and had the "brilliant" idea to execute the recommended updates. Restarting the computer I just saw for a couple of seconds the blip up left and then a black screen. Nothing else happened. Posts to the French Ubuntu forum yielded no solution, so I decided to reinstall 10.04 again. It worked well a couple of times, and then again I had the black screen and no boot. How can I delete the installed versions?

My brother has been a long time Linux fan, and has been getting on me forever to dual-boot my computer with Linux. So I finally got around to it and dual-booted it with a partition, and it works just fine, problem is all my stuff is on the Windows 7 partition of the hard-drive. I hear the big Linux feature is being able to take everything from the Windows side of the computer and transferring it over to the Linux side...
My only question is, where would I find that feature? I browsed around the administration system capabilities but couldn't find anything related to the partition, so I could use a little guidance in finding the feature, or whether I need to download a program to use it.

Current set-up:
Athlon 64 2800
2 GB RAM
340 GB on two HDD
Ubuntu 10.04 LTS
Win XP Pro SP3
After getting the Silver Ghost all set up and purring like a kitten for my daughter, she now informs me she'd rather have Win7 HP instead of Win XP Pro SP3. Ubuntu and Win XP Pro are on separate HDD. Can I do a "clean install" of Win 7 HP on the Windows drive without screwing up GRUB? Or will I need to do the dance described at [URL]. I've had to modify Ubuntu because of conflicts between 10.04 and the Ralink 2780 (?) wireless-n drivers.

Win-7 Ubuntu Dual Boot, Drive Presence Issue I recently built up a new computer and set it up for dual-boot with Win7 and Ubuntu. Initially I had some issues with the boot management but I discovered that GRUB works well and Paragon's Partition Manager does not. I reloaded Ubuntu using GRUB and got the system working exactly as I would like it to. Several weeks later I volunteered to assist my brother-in-law's family with getting their Unbutu system working properly with a new Brother MFC295CN printer. I brought the printer home so that I could work with it on my system.
I did get the printer to work correctly but in the process I had to reload Ubuntu because I made a few mistakes on my way to success. When I reloaded Ubuntu, I accidentally loaded it onto my system's second drive, drive F. Before, I had Ubuntu in a partition on drive C. Ubuntu works from the F drive and GRUB allows me to boot either Win 7 or Ubuntu, as desired. I will note that the earlier version of Ubuntu on drive C has been removed although the partition is still there. GRUB shows entries for this second copy of Ubuntu along with Win 7 and the entry for the functioning Ubuntu OS.
Here's where I am getting into trouble. Initially, everything looked fine. Win 7 worked, Ubuntu worked. Then, after a reboot to Win7, I noticed that my F drive was missing. I searched all around the system controls, tried loading new hardware, etc, etc, but the drive did not show up anywhere. Rebooting into Ubuntu showed that the drive was in fact still there and all the date in the large data partition was still there. Using Ubuntu's partition manager I discovered that the data partition was not enabled. I enabled the partition and rebooted back into Win7. No go.
The F drive was not present. My next step was to try Paragon's Partition Manager software, which I have a paid-for copy of. It would not see the F drive either. Using the Paragon recovery disk I had made earlier with the Paragon software, I restarted the system. The recovery software saw both drives correctly and the partitions were set up correctly. I ran the boot corrector software but I did not mess around too much as earlier experience had indicated that some of the Paragon features do not work well with Ubuntu. I shut down and rebooted into Win7. Success! The F drive was there.
But later, when I restarted the system the F drive was gone again. I tried a few things then rebooted using the recovery disk again. As before, on the next restart the F drive was present. I didn't take the time to reboot the system twenty times, but it seems apparent that something in the boot records is preventing Win7 from seeing the F drive correctly unless I boot from the Paragon recovery disk and then boot Win7.
No knowing a lot about what goes into a boot record and how either GRUB or boot.ini manage things, I am at a loss as to why I'm seeing this inconsistency with the F drive. A probable solution would be to remove both the second (old Ubuntu) partition on the C drive and the Ubuntu partion on the F drive and reload Unbutu all over. This would put me back to where I was in the beginning. However, this seems a bit inelegant as all the other attributes of the system are working well, is there a better way to address the problem?
