Changing Partition System - Windows 7 Can Only Be Installed To GPT Disks
May 30, 2012
As Windows tells me, "on EFI systems, Windows can only be installed to GPT disks". This is the error message I get trying to install a Windows upgrade from 7 Home Premium to Pro. I have to do a custom install because I am installing English over Russian. I have looked on the internet about how to change my partition system to GPT. Seems like something I can do, however, I have a question: If I have only one physical hard drive in my machine, is it possible the change the partition system from MBR to GPT? I see lots of examples of doing it to a second hard drive, but not many when it is the only hard drive. It is a new drive and clean, so I do not worry at this point about the data on it.

Earlier I had two partitions, D(logical) and C(system). Now, I have added a new HDD and I've made two new partitions, B(logical) and S(system), now I want to format C and install Windows in S partition.

I'm sure there's probably a tutorial for this somewhere in the tutorial index but I can't seem to find it.
I have 3 partitions on my hard drive. C is for Windows 7 32 bit Ultimate, D is for Vista 32 bit Home Premium and E is a recovery partition. My problem is that I want to delete my Vista partition and then expand my 7 but there's one thing in the way.
D is my system partition. What I want to do is make C my system partition. Just as an extra bit of information, here's the status
E: Healthy, Primary Partition
D: Healthy, system, primary partition
C: healthy, boot, page file, active, crash dump, primary partition

I decided to Dual boot Hackintosh (iDeneb) and Windows 7 on my HP laptop. I got OS X up and running and I can't seem to repair my Windows 7. The installation disk can't find and fix the problem automatically, so I went to Command line prompt and when I type it Bootrec.exe/scanOS is says that it can't find any installed windows on the disks. I am 100% sure I did not over write my windows partition with the OS X and honestly, I have no idea how to get Windows running again without having to install from scratch.

I wanna re-size my partition disks. I have C: and D:, I want to shrink C's volume, and extend D's, is it possible without a format? If so, how? (I don't care if it needed a 3rd party program).If I need to do a format to get this done, how to?

I've installed Win7 on a 500GB Sata II disk and was running fine. Then something happened, boot manager missing, and I need to re-install Win7 on same disk. Now I get a message, when installing on the SAME DISK: "Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks."
This disk just had Win7 installed on it and is still there (but boot manager is still missing) so how can the disk have an MBR partition? I got this same msg. when trying to install Win7 on a clean Samsung 128GB SSD as well. I re-formatted the drive and still same msg. How can I make my disk formatted with GPT partitions instead of MBR partitions? I can find no choices in terms of which kind of formatting and partitions that can be used when formatting disks on Win7 or XP Pro.

I have my HP Laptop which came with Windows Vista as the OS. I want to upgrade to Windows 7 so I bought Windows 7 from my local store.I entered the disc and did boot from CD. It reached to the page where it shows the disk partition. I deleted the partitions and created new one. However, whenever I create the partition, it creates a primary one and gives me error saying Setup was unable to create a new system partition or locate an existing system partition.

I have a custom built HTPC running Windows7 Home Premium 64 bit that I bought from a tin-pot PC building firm last year. It has 4 physical drives in it. The first is configured as a "basic disk" with a single C: drive partition on which windows 7 is installed. The other three are configured as a RAID1 "dynamic disk" that present themselves in Windows as a single logical drive (E:) and that's where all my data lives.Windows Media Centre has now stopped working properly and I've tried everything to fix it, in case I can avoid a reinstall! mcupdate.exe always crashes(with System.IO.FileNotFoundException): I can't update TV signal set-up or guide data ) so now I need to reinstall windows. I'm an IT professional and I've installed many prior versions of windows in the past, but never Windows 7:
1) If I reinstall Windows 7 on my C:/ drive, will the E: drive be left unaffected and the fresh install of windows will still be able to see the E: drive and access all the data on it without any permissions issues?
2) The company that I bought the HTPC from neglected to give me a DVD with the Windows 7 installer (and prod key) on and they went out of business a few months ago, so I'm feeling a bit stuck. I've used a free tool to extract my Windows 7 product key from the registry, and borrowed a Windows 7 DVD from a friend. Will reinstalling from this DVD with the product key I've extracted work, or is the product key tied to the physical DVD (or does it just need to pass a checksum algorithm?) If I use my product key to reinstall, will I also be able to re"activate" Windows 7 or will it now think it's a dodgy copy? My current install says it's an OEM version (when I tried to get support from MS.com), but my friend's DVD is a full retail one - is that a problem too? What options do I have here? Can I, for example, create a copy of my friend's DVD and amend the prod-key in the poduct.ini file to be mine in the "HomePremium=" entry?
3) Before I attempt anything, I'm keen to do a full system backup. I've done this with the Windows 7 system image tool and have a 154 GB file that I've copied to an external USB hard drive, and I'm going to create a restore boot "disk" on a CD. However, If I need to do a restore, can the restore app read from a USB HD or not? I assume it can't read from the dynamic disk E: drive? Or can I just keep it on the C: drive, or will this get wiped completely when I reinstall windows, thus losing the image file?

I have a copy of windows 7 from a friend. (USB, possibly enterprise)It runs well, is official and can be re installed and is verified through the Microsoft site, so the media doesn't seem to be a problem.I was able to install Win7 Ult x64 on my WinVista HomePrem x86, but I went back through to clean the hard drive (it was full, I didn't format before) and after low level formatting I cannot reinstall the OS. The harddrives are completely empty, and I get stuck at "Setup was unable to create a new system partition or locate an existing system partition," after hitting next when you are selecting the HD partition to install on. I tried a couple of things already:
-Installing on another harddrive
-Formatting using Hiren's bootcd
-Using a hard drive with XP installed to see if it is an upgrade and not a full version (no luck, still wouldn't install)
-diskpart > list disk > select disk 0 > list partition > active \ in cmd..I have three hard drives attached to the computer right now, they can't all be broken. T.T

I currently have a dual boot on my computer with Windows 7 and XP. Unfortunately as my computer is quite old my hard drive is not very big and with it being partitioned I am fast running out of disk space. So I tried to shrink the XP partition to allow me more disk space for Windows 7. Unfortunatley this would only let me shrink it by 83mb for some reason. I decided that since I barely use XP anymore that I would simply reformat the XP drive then try and merge them together. When I tried to format the partition it just gave the error "Windows was unable to complete the format". I then discovered in Disk Management that the Windows XP partition was the system partition which was causing the problem.

Through a series of shenanigans involving experiments with mirroring on Windows 7 64 bit using Disk Management, and then subsequently removing the mirror after having recurring errors/problems with the synching, My 100MB System Reserve partition has ended up on a separate partition than my system image. For instance: Disk 1 System C: Healthy (Boot, page...) Disk 0 Healthy (System Reserved...).
In addition, the System Reserved partition has been assigned a drive letter "G:" or "E:" and is now visible in explorer and it won't allow me to remove it and supress from explorer view.
I'd like to
1) move/create the System Reserve partition to Disk 1 (with System C: drive)
2) remove the System Reserve partition from Disk 0 to free it all up as a data drive
Do I use command below to create a System Reserve on Disk 1? bcdboot C:Windows How do I then delete the System Reserve partition on Disk 0. Also a byproduct of all of this, when I reboot now, I have a "Windows 7" option and a "Windows 7 Secondary Plex" option. The "Windows 7" option no longer boots (it's stops while the logo panes are flying in circles to form the logo and goes into a fix loop that never fixes it). I have a feeling it's looking for the old mirrored hardware configuration or something. However, "Window 7 Secondary Plex" option does boot just fine. Do I use MSCONFIG to remove the "Windows 7" boot entry so I don't get this annoying option at boot?

So in the last month i noticed some of my folders i keep on the desktop change form the newer slicker icon of a folder back to the typical windows yellow folder. Then more and more until all of my folders where like that.Then all of sudden some sounds started to go from a normal contemporary notification sound to a dull sound from XP or older.Then about a week ago the "bar" if you will changed from a typical Win7 style back to a XP one where its dull. And its like that everywhere.
I have tried icon programs at first to fix the folder issue and unless i wanna do it one buy one its sucks and i just want them back to a normal win7 folder nothing fancy.I have tried changing themes via the ones pre installed and it might change my desktop wallpaper it never changes the "bars"Also tried other non microsoft theme programs with the same results.
ALSO i scanned my pc with Malwarebyes, CCleaner, WinASO, AVG and cleaned all up and so on rebooted all the same.Thought i may have installed too many apps or at least big apps (photo/video editing) and i uninstalled a few with no difference.So then i decided to check out my ram. So i make a bootable disc of a memory scanner. Ended up getting into the millions of errors with the ram i had and i stopped it before it was done with the intentions on getting ram and not waiting until scan was done to tell me i had 500 trillion errors lol.
Bought new ram installed it started her up and BAM .... same thing.I have not scanned this ram as my wife uses it while im at work and when im home i do alota 2nd job stuff on it so i dont like having it offline long.

So if I just click on next I just get an error message of"Setup was unable to create a new system partition or locate an existing system partition.

So long story short, my current os (w7) is installed on a non-boot partition of a now internal drive that used to be external. This wasn't an issue/I didn't notice because I had another unused internal hdd which DID have an old bootable os partition, and then I'd just choose the correct instance of Windows when that one booted.I have to get rid of the old HDD with the bootable partition. Is there anyway I can change the non bootable my currant OS is on to a bootable partition (ie thru windows, cmd, bios etc)

Suddenly my Win 7 Home Premium x64 will not boot. The system starts, POSTs then loads the DVD driver, then the screen goes black (not blank but "lit up" black if that makes sense). Then nothing. If I use Hiren's boot cd I can boot up using the "boot from HDD" option fine and Windows operates normally. System restore to a previous configuration made no difference to the original problem. I cannot boot into Safe Mode. F8 just offers me boot order options.
- Running the Windows 7 DVD I find: "No operating system is listed on the Repair Windows option."
- Running Startup Repair finds the following error: "the partition table does not have a valid system partition" which it claims to have repaired, but the error remains and Windows will still not boot.
I followed this advice:
Boot 7 dvd to system recovery options command prompt. Type: Diskpart
list vol (find the vol letter e.g C or partition number e.g. 1 for the system partition )
Sel vol C ( or sel vol 1, obviously use the correct letter or number)
act exi
My system partition was easily identified and listed as healthy so I selected it and made it active. The problem still remains exactly the same. My system is self built just over a year ago, to my knowledge has been running fine, without any hardware issues. I'm prepared to do a clean install if that's what it takes but if there is a way to fix the partition problem without that I'd like to explore it first.

So I've got an ASRock motherboard that's about 3 months old and I'm running Windows 7. Earlier today, I started having a strange problem with the system time changing randomly. At first, I thought it was just a daylight savings time issue, so I disabled the automatic updating for daylight savings time. The problem still persisted. I also tried disabling the automatic time synchronization, but that didn't fix the problem either. I thought it may have been the CMOS battery, so I rebooted and checked the time in the bios. The bios shows the correct time/date. The only incorrect time and date is shown in Windows itself. After this, I tried updating the synchronization task to run every 5 minutes, but the clock is still changing to a different time. The time change is random, from around an hour to up to six or seven hours. The date doesn't change, just the time. My timezone is correct, and as the problem persisted without having automatic adjust for daylight savings time enabled, I can't see that it's the problem.Does anyone have any idea what could be causing this? About the only idea I have left is some sort of virus. But AVG and Malwarebytes haven't picked anything up. Is there some kind of software that gets auto-installed that can screw with system time?

So, I have a disk with Windows 7 installed on the 3rd partition of that disk. I want to move that installation to the first partition of the disk.Repartitioning and boot settings aside, is there a way to do that? (besides using sysprep)Last time I tried that, windows would load slowly and after ''Preparing your desktop'' screen it would just show the one-color desktop, no icons, no explorer shell loaded.Alt,Ctrl,delete works, for running ''explorer'' from task manager, but computer, control panel or anything system-related does not open, instead it pops up an error window with, (e.x.)''{ED7BA470-8E54-465E-825C-99712043E01C}'' not found.

I'm trying to do a clean install on Windows 7 64-bit on my laptop. I currently have 32-bit Vista running.I initially created a new partition, copies all my data there, then started to do the custom install. I got the message: Quote: Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks. Quote: Esc when booting to take you into the EFI boot manager and select DVD-Drive instead of ACPI (....) string I have tried to go in to the start-up options but I don't see this option. I just keep getting back to the above error message.I have since deleted my extra partition, and intend just re-syncing my laptop's data via Dropbox (9GB - hope it will be ok!).
