Preferred Solution: Dual booting Windows 8.1 x64 Windows 7 x64. Then added SSD Windows 10 tech preview

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

You probably refer to this registry fix. It is working when you dual-boot Windows and Linux, but I never heard of such a time problem between Windows 10 & Windows 8.1. Is your local time actually UTC+4?

I have a computer with two hard drives in it. I have Windows 8 Release Preview installed on the first Hard Drive and I wanted to install XP on the second Hard Drive to be able to play older games that Windows 8 has issues with.

My first attempt didn't work. I installed Windows 8 on the first Hard Drive then tried to install XP on the second hard drive, it formatted it, copied the basic files then started the windows setup and crashed on the device installation section. I rebooted the computer and it only restarted in XP, came to the same point and crashed again with a blue screen with 'IRQL_NOT_LESS_OR_EQUAL' message. When I rebooted with and tried to boot into Windows 8 with the system boot menu, it crashed.

I have tried google info, but most people suggest disconnecting a drive, setting up a OS and then doing it for the next OS on the next drive. Others suggest partitioning one drive.

I would like to have Windows 8 on one drive and XP on the other with a boot menu at the start like my son has with his Windows 8 and Windows 7 Dual boot.

I hope someone can help.



A:Dual Booting Windows 8 Release Preview and XP on two Hard Drives

Try in the reverse order , format both drives to ensure they are cleaned up.
Install XP first on the first hard drive available , which is the boot drive.
Check it boots correctly.
Then install W8 and then choose the second drive it should then overwrite the master boot record on drive 1 to allow dual booting but installs windows8 on drive 2. ( Installing xp second overwrites the MBR on the W8 type of dual boot record.)
Hope this helps.
But personally if you are using 2 completely different drives and can choose which one boots first in the bios by some means (pressing F12 key on mine), I would do so individually as per the suggestion you found on Google. Iit gives you more flexibility to install and change drives around without the sort of problems you have run into.

So recently, I've installed Windows 10 on a separate partition on my 500 GB hard disk that's about 40 GB, and it works perfectly. Except that I can't boot back into Windows 7.

All of my files are still accessible and working, I just can't actually boot into the OS. When I attempt to through the Windows 10 boot screen, first it reboots, then it goes to a black screen with 8 short lines of bright blue pixels on the top left. After a couple of moments, multi-colored pixels start appearing and changing all across the top couple of lines of pixels. This happens in the course of about a minute or so. I usually give up and turn it off cause I notice there is obviously something wrong.

Is there anything I could do to fix this? I've looked everywhere to see if anyone had this problem, but I couldn't seem to find anything.

Thanks in advance!

PS: This is my first time using this forum, so excuse my nooby mistakes.

Hey guys, I was thinking about trying out the Windows 10 Tech Preview on my laptop and was wanting to know if I didn't like it if it was possible to get my laptop back to factory condition in which it came which is Windows 7 Home Premium, this laptop has a hidden partition that has the original "out-of-the-box" state and if upgrading to Windows 10 Tech Preview would erase the hidden partition.

Okay, this is gonna be a doozy of a topic, so let's say what happened.

I got a Venue 11 Pro in the mail yesterday. Just the tablet. Don't have the keyboard dock yet. The model with 8 Gigs of RAM and an i5 processor if that helps.

Windows 8.1, so I installed the Windows 10 Technical Preview and everything looked good.

So I installed Google Chrome and when I pressed "Open in Windows 8 Mode" It got glitched out. Wouldn't load properly. Was weird. So then I restarted my PC.

After restarting the PC, it still wouldn't work. And the start menu wouldn't load. Like I'd tap the start button, hit the tablet's start button. Nothing. I could right click it and use those options, but the start menu wouldn't come up.

So I tried to do a PC Refresh and this is where things get crappy. It started the refresh and said it was 8% done.

Went to bed and woke up about 5 or 6 hours later and it was still at 8%. Waiting a few more hours. Still at 8%. Then, I did the dumb move of manually powering off the PC since it seemed to be frozen on the refresh after nearly 9 hours at the same percentage.

After that happened, it would only boot to recovery options. So, I tried to do the recovery that wouldn't affect your files. Had an error that it couldn't complete. So I tried to "completely reinstall Windows" option. And it resulted in this:

"Your PC Needs to be repaired. Error Code: 0xc0000034" It did not have a BCD section on... Read more

I put my HP laptop on sleep. Then I woke up and tried to turn it on. It turned on but was on a black screen. Normally black screen is for up to 5 seconds before something shows on screen but this time it was more than 5 mins and nothing so I rebooted it. The computer said updating because I had a pending restart. It updated then rebooted and said fixing disk errors (don't know why) then after it finished, it rebooted again and said preparing automatic repair. 5 seconds later it crashed with a bsod but was to fast to find out what the error was. I found out it was driver irql not less or equal something like that. It keeps looping auto repair 5 seconds later bsod. I tried f8 and startup settings but it keeps coming up with a screen saying recovery your pc needs to be repaired with error 0x000000f.

What should I do? I can't boot anything up or go into start up settings if I needed to get to safe mode or other things. No CD driver neither. I downloaded Windows 10 and copied its files to a flash drive then realized it was Portuguese copy BUT even though I don't know what to do with the flash drive booting from efi file or something like that.

So, I was thinking about installing Windows 10 Technical Preview on my computer. But, now I have backed out due to concerns of it not being finished. My problem is that the Windows Updates icon in the Notifications Center keeps saying Windows 10 Technical Preview is ready. I have already hidden the 10 Tech Preview Update. How do I get it to stop saying this?

A:Notification Center: Updates Icon Keeps Saying Windows 10 Tech Preview

You must have intended to try Win10 and record of that attempt has been saved somewhere on your computer.
Press Windows key plus R then type msconfig in the Run box, under the Startup tab Uncheck anything relating to Windows 10 TP. If you do Uncheck something you'll be prompted to reboot. In some cases a brute force procedure is needed and usually required editing the Registry, not a place for the inexperienced to play as one misstep will cause Windows to not work.

So I've recently bought an SSD Drive soley for the purpose of running Windows. The original Hard Drive was a 2TB Samsung drive that I have since formatted and using for Storage only. Installed Windows 10 on the SSD and the machine is working great, boots up in aound 10 seconds from turning the machine on.

Now heres my issue. For some reason if i turn my PC on and do nothing it will show the message no operating system found press ctrl, alt + del to restart. This is because its still looking to my original 2TB Drive to boot up. So basically I have to tap F something everytime i turn my machine on and select the SSD from the list.

Here is where things get weird. I have gone into the bios and have the choice of what the machine boots up with, so again i can select my SSD. The problem is the section where I can set the boot order default is only showing my 2TB Hard drive and the Blu-Ray drive, the SSD doesnt appear in that list. So it appears in one time boot options but not in the boot priority list so I cant set it as the default Drive.

Can anyone think as to why this could be?

Any help would be much appreciated.

I have another laptop and its a HP 2230s. I originally installed Windows 7 professional 64bit. But I have swapped the ram into my Lenovo ThinkPad. So the HP now has 2GB. I created a new partition and installed Vista Business 32bit on it. When I started the install windows .exe program in Windows 7, everything went well until it rebooted. When I rebooted, windows said something like:

Windows Boot manager:

The system cannot boot because of a recent change to files/hardware. (Something like that). Insert your windows disk.

So I just rebooted my laptop with the vista disk inside and installed. After, when everything was working, I wanted to go to the Windows 7 partition to un-install programs and copy some files over to the vista partition, the laptop just booted into vista.

I downloaded the easy BCD editior and visual BCD editor. (in the vista partition), I clicked the auto fix in visual BCD editor. It detected my windows installations. At the boot screen, I can select either Windows 7 or Vista. But when I select 7, the same error message appears.

Then I rebooted my laptop with a USB containing the Windows 7 (64bit) recovery tools. After, I don't have the message again. But when it goes to the starting windows animation, it stops halfway and it gets a BSOD. I tried debugging mode, it worked.

I found out that the larger partition, (Windows 7) is the C: drive. But when I boot into the smaller partition, (Windows Vista), the drive is also C:!. So I do... Read more

First of all I would like to say thank you for allowing me to join the forum. Back in 1999 when I was medically retired from the British Army after sustaining a spinal injury on Operational Tour, I retrained myself in computers. My OS of choice back then was MS Windows, however after Windows XP I moved to OSX.

About two years ago I knew I needed to get back involved with Windows and bought my Lenovo Laptop running Windows 7 Home Premium. I then installed Windows 8 Consumer Preview on a different partition and upgraded to Windows 8 Pro when it became available.

I am now looking to install a distro of Linux and can't seem to find any information of doing so. I don't know which Windows partition it would be best to install it on 7 or 8. Also I understand that Ubuntu have a Windows Installer wubi, but I have heard horror stories after the installation.

My main fear is losing Windows 7 or 8 and if the entire process is too risky I'll just leave it altogether. So I guess my question is has anyone installed a Linux distro on a PC which originally came pre installed with Windows 7 and then added Windows 8 to a partition; if so can you help me out. I apologise if this question offends anyone who may think I should have posted this on a Linux forum, I just thought I would get a more concise answer from the Windows Forums.

thank you all so much for your help and time in advance.

A:Windows 7 and Windows 8 dual booting then adding Linux

It would be best to install your Linux distro on another HD with the WIndows OS HD unplugged. You can even run Linux from a boot CD or flash stick.

If you decide you want to try multi-booting it with Windows I'd back up a Win7 backup image of your Windows installations first so you have a path back to where you are now.

I'd also look over this tutorial written by one of our top members here: Dual Boot - Windows 7 and Linux - Windows 7 Forums.

You can discuss this further with the tutorial's author in its comments section or ask him there to chip in to discussion here. You'll get help that like him is Golden.

On your system, all you will need is a second partition (or hard drive, your choice), and then you just need to install NT, it will create a dual boot system automatically.

The most annoying feature of dual booting, or indeed, running a different Windows version in a VM, is that Windows updates have to be done for each OS, if I want to keep both OS versions current and secure. On the second OS, which may be used just occasionally, the entire cycle of download, installation and then restart and configuration of the updates can take a long time. This obviously can disrupt work, or the updates have to be manually interrupted, and delayed for another day, when the second OS attempts to finish the updates, giving a further wait before the system can be used.

Windows 8 can schedule the updates to be done out of hours, but forces a restart a day or so later. Windows 7 forces the restart sooner.

Has anyone a script to schedule an update of the other OS following "patch Tuesday", when either one of the OSs has done an automatic update - with either version acting as an updates server for the other OS?

Here's the scenario I'd like: Windows 8 receives automatic update downloads for itself and then for the other OS, and at a scheduled time, installs its own updates, then shuts down, starts the other OS, which installs its own updates, and then restarts and completes the installation. Now, the Windows 8 system restarts, completes the configuration of the updates for itself, and then the system is ready for use the next day.

Now if the active system at the time of update is Windows 7, the same procedure takes place, with Windows 8 as the other ... Read more

I have windows XP installed and can easily shrink the partition it's on to make room for windows 98. However, every guide to dual booting says I must install windows 98 first, but I already have windows XP installed with all my programs and definitely don't want to have to reinstall it and all my programs as well.

Is there any way? What about another boot loader which can handle them both and how would I install it.

You have to install Windows XP only after installing MS-DOS, Windows 95, Windows 98, or Windows Me to prevent these operating systems from overwriting the Windows XP boot sector and the Windows XP startup files.

Could I just use a different boot loader? I could install 98 on a different partition so it doesn't even know Windows XP is there, then install a boot loader to let me choose?

I've never done this before, so it's all knew to me, this dual booting. I have an extra HDD (in my PC)and I would like to test out windows 8 on. What are the difficulties involved in this process? What version of windows 8 preview should I attempt to use?

A:dual boot windows 8 preview

There is no concern in dual booting Windows 8 with Windows 7. Just boot up with the Windows 8 DVD, select the extra HDD in which you will install the Win 8 OS and you're good to go. In this case, you're actually not dual booting, you are just installing a different OS on a different hard drive. So you will need to change the boot order in BIOS to boot to the required OS.

Or another option is to shrink the size of C drive and create another partition out of it. Then install Windows 8 on the newly created partition. This is dual boot in true sense.

    I recently bought a new Lenovo Thinkpad E455 64bit (8.1 Pro upgraded to Win 10 Pro) to replace my Toshiba Satellite 32bit (Vista business upgraded to Windows 7 Pro) and bought a SSD so I could dual boot between the systems. I used EaseUS
Todo to clone both systems to the SSD and got the Windows 10 working wonderfully, but cannot boot to Windows 7 without a blue screen of death that consistently refuses to allow me to repair it with my repair disk.

    The Lenovo doesn't have a CD drive, so I pushed the repair files to a USB. Still not working. The laptop just won't boot from the USB or give me the option to repair. And I can't create a Recovery Drive because I don't have a Windows 7

Hi, I just made a new installation of Windows 8 Pro.

Before installation I had Windows 7 Ultimate 64bit with same computer specs minus the Samsung SSD disk.
My intention was to make a dual boot system with both Windows 7 and Windows 8.
However, due to tiredness and common confusion I think I did some mistakes.

I don't think I had an Uefi installation so probably an mbr installation of Windows 7.

Ok, so here goes: I started with installing the new Samsung SSD disk in my system, I forgot to disconnect the other drives before starting Windows 8 installation. However, at first I could dual boot but I couldnt see my 2TB disk in Windows 8. I assigned a drive letter to it and then my problems began.

I can now start Windows 8 and see all 3 disks and use them as well. If I try to boot into Windows 7 on my OCZ drive I get a disk error.

I guess I messed up the mbr boot table. My question is, how can i fix this best?

Most important is to not loose my Windows 7 installation, I can Always make a new installation of Windows 8 as it is still fresh.

This is how my system looks now:

Operating System Microsoft Windows 8 Pro with Media Center 64-bit

Then I put the windows XP installation disk in and restarted my computer, I then went on to install Windows XP on the F\ drive, after setup had installed the basic files it restarted the PC and now I get a message asking to boot from CD, I do so and then it tries to start set up over again.

I can't get past the CD booting part (my CD ROM is primary in boot order) so I can't use Windows Vista which is already installed, or finish off the Windows XP installation.

Computer specs:
500GB Hitachi HDD SATA-2
4GB Kingston DDR2 RAM
AMD Athlon 64 X2 3.2GHz processor
XFX GeForce 9500GT 1GB PCI-E

If anyone could help it would be greatly appreciated.
Kind regards,

Once XP has copied files it does reboot and you will see press any key to boot from CD again only now you do not press anything and setup should continue at that point.

Do you already have Vista installed on your PC?

For the last 2 years I've had my PC setup to Dual Boot from either Windows Vista Home Premium Edition x32 or Windows 7 Professional Edition x64. The Windows Vista drive had only a capacity of 34.4GBt and had given up the ghost. So I chose to format and re-install Windows Vista onto this small drive. The drive is working like new but now the PC boots into Vista and I cannot boot into Windows 7. I know that I should get a hold of the Windows 7 installation disk and repair the installation but unfortunately I've been moving around a lot and can find everyone of my installation discs except the Windows 7 Professional. Can anyone offer me advice on how to re-establish my Dual Boot without the use of an installation disc? Any advice would be appreciated.

You could try Easy BCD. But more then likely you will have to download the Iso and do a startup repair.

A:Dual booting windows xp and windows 7 problem

Hi Rudolph, welcome to the forums
Can you give more details? Have you been able to install Windows 7? Did you already have XP installed? If not are you trying a clean install or upgrade? Have you started booting from the DVD or running setup.exe

Can you also double check the message? There seems to be nothing about "TFGHT"

Hello. I am trying to figure out how to dual boot Windows 2000 and Windows ME? I know that you can partition your drive but is there a way to dual boot using a Master/ slave drive? This would be ideal for me. Any advice and/or good links would be greatly appreciated. This is actually for an older HP computer I have. thank you

A:Dual Booting Windows 2000 and Windows ME

What I would recommend doing is installing Windows Me on the slave drive first, making sure it is bootable and what not. Then installing Windows 2000 on the master drive. Windows 2000 should see the Windows Me installation and pick it up. Then when you go to boot your system the Windows Operating System loader will appear and it will ask you if you want to boot to "Windows 2000 Professional" or "Windows Me".

You could also use Norton PartitionMagic, it used to be PowerQuest PartitionMagic but now I think it is owned by Symantec.


There is some information about Symantec/Norton PartitionMagic.

I am dualbooting Windows 7 and Vista. So far everything is running perfect. The only thing I am having a problem with is running programs from my Vista partition.

One game won't start at all and Steam tries to open, but then says it can't find a key. How can I run programs from my Vista partition without having to reinstall? I don't have a lot of space to spare. That one game I was trying to run takes 7 GB.


A:Dual booting Windows 7 RC and Windows Vista SP1

You don't. The only way to run a program in 7 is to install it into 7. The drivers, auxiliary files, application data and so on can't be used from an operating system that is not loaded.

I recently upgraded my copy of Windows 7 to Windows 8 (using an upgrade-DVD), now after using it for a while I'd like to have the option to boot up Windows 7 too. Unfortunately I only have a windows 7 upgrade DVD so I'll have to install windows vista before installing windows 7.

Now here's what I'd like to have: the pc should have Windows 8 as the primary OS, and windows 7 as a secondary OS. At this moment windows 8 is installed in my C-drive. Is it possible to just install windows vista in a freshly made partition?

I thank you in advance!

Hello, today I am trying to dual boot my Pre-Installed Windows 8.1 Pro with Windows 7. I have chosen "Shrink Volume" in Disk Management and I have created a new partition for Windows 7. Whenever I try to install windows 7 on the selected partition, I get the error that the hard disk is GPT type. I cannot convert it to MBR.
I only see "Disk 0"
I write "select Disk 0"
Then I write "List Partition"
My hard drive has 7 partitions. My windows 7 partition is 5
I write "select partition 5"
Now, my question is, if I write clean, will it clean that specific partition or my entire hard drive?

Boot from the Windows installation media in UEFI Boot Mode, so you can use GPT (GUID Partition Table).

Quote from this post: UEFI Boot Mode (installing using the GPT partition style) and Legacy BIOS Boot Mode (installing using the MBR partition style). -> link

Error message when you boot from the Windows installation media in Legacy BIOS Boot Mode:

Windows cannot be installed to this disk. The selected disk is of the GPT partition style. (see screenshot below)

That is because Windows can only be installed to MBR disk in Legacy BIOS Boot Mode, but you plan to install Windows on a GPT disk.

- Boot from the Windows installation media in UEFI Boot Mode, so you can use GPT (GUID Partition Table).
- But if you want to use MBR (Master Boot Record) partition table, then delete all partitions on the disk.

Hi there I'm desperately trying to install two of the SAME installations of windows xp on two seperate SATA hard drives and successfully dual boot them. I had a previous windows xp installation on my master sata drive, and made made another sata drive (formatted) as master, then installed windows xp on it as well. My problem is when I boot up I don't get a boot loader that i've been told will be installed automatically by windows installation. The only way to switch between the installations is in the bios. PLEASE HELP! I'm really keen to get my two installations up and running. I want to use one for general net browsing, movie watching and music and the other solely for gaming.

Hi mikehoneyman and welcome to TSF !

Try this : go to start => run and type msconfig. Go to the boot.ini tab and click on "check boot paths". See if it detects the other installation and adds it to the boot.ini file.

You could also edit the boot.ini file yourself : right-click my computer => properties => advanced => settings under startup and recovery => edit. Don't change anything in the line that's already under [operating systems] and add the line corresponding to your other hard drive. See this link to know how to provide the exact location of the second installation :
The easiest would be to load the other installation and look directly in the boot.ini file.

A third solution would be to use the bootcfg utility :


start the computer from the Windows XP CD, start the Recovery Console, and then use the Bootcfg.exe tool to rebuild the Boot.ini file. To do this, follow these steps:
1. Configure the computer to start from the CD-ROM or DVD-ROM drive. For information about how to do this, see your computer documentation, or contact your computer manufacturer.
2. Insert the Windows XP CD-ROM into your CD-ROM or DVD-ROM drive, and then restart your computer.
3. When you receive the "Press any key to boot from CD" message, press a key to start your computer from the Windows XP CD-ROM.

Alrighty guys.
So after spending hours reading forums and stuff, I figured out how to install Windows 8.
I followed all of the steps. But now, I am unable to boot into Windows 7. When I try, it comes up with this screen that says

Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your Windows installation disc and restart your computer.
2. Choose your language settings and then click "next."
3. Click 'repair your computer'.

If you do not have the disc, contact your system administrator or computer manufacturer for assistance.

Okay, so I have a Lenovo V570, and it has two internal hard drives (See picture)
would it be a bad idea to install windows 8 to the lenovo drive? (Correction! It's just one drive. The one I am talking about is a partition of the original C drive!)
Because I was going to dual boot it on one hard drive but I have so much space on the other, I didn't know if that was a better idea. Please Help!

Hello all,

I have a question here: Thinkin of dual-booting Windows 7 with XP, but i'm just wondering if you, for example get tired of Windows 7 and decide to remove it, what's the best way? Pop in XP disc and do a fixmbr to restore XP's originally MBR and then go and use Gparted or Partitionmagic for example and delete the partition, format it, and then merge it with the main partition.

Recently I purchased a laptop with windows 8 64 bit pre-installed in it. For my job purpose, I needed windows 7 32 bit. After searching the web and also using the information I got from this site, I disabled secure boot, deleted the recovery partition and converted GPT partitions to MBR. Then I shrink the Big partition in which windows 8 was installed to make room for the windows 7 partition. Then I created a new partition and installed windows 7 on it. After this whenever I switch on the computer, a message come up, saying that a required device cannot be found and windows is to be repaired. The only way in which I can start windows is to go to bios, select the boot options and then select boot from notebook hard drive.

Can anybody please tell me how this problem can be solved

A:Booting problem with dual booting with windows 8 and 7

when you created the new partition did you make itin front or behind the existing partition?

If your boot manager is looking to boot Win 8 on Disk 0 Part 1, and you created the new partition in front of Win 8, your Win 7 will now be located on Disk 0 Part 1 which is where the boot manager is expecting Win 8

can you send us a screen cap of your disk management?

I currently have XP, considering upgrading to 7 (64bit)

I'm a little scared i'm not going to like 7 so want to hang on to XP as a back-up.

What I want to know is, using cloning software (I think i'll either use the seagate software as I have a hardrive or two of theirs (Acronis) or XXClone) can I clone my XP system on to a separate hardrive, upgrade to 7 from there and boot from the separate HDD's while I decide?

Will the licences get grumpy cos i'm running from the same copy of XP?

I've never actually tried cloning before so i'm also a little worried that the XP clone wont work to start with (after forking out for a new HDD to clone to)

Thanks in advance

Make sure your Hard drives or the partition which XP is on is big enough and has enough room to make a partition for Windows 7.
