Can't Install Win7 On GUID Partition Table
Sep 21, 2009
Is it possible to install Windows 7 on a GPT disk?
I created a RAID 0 array on my dual Xeon 5580 system and tried installing Windows 7 Ultimate 64-bit RTM. When I got to the "Where do you want to install Windows" part I used shift-F10 to open up a command window, then I used diskpart to create a GPT with the following partitions:
Disk 0 Part 1 - 102 MB EFI System
Disk 0 Part 2 - 128 MB MSR
Disk 0 Part 3 - 500 MB Primary
Disk 0 Part 4 - 7446 GB Primary
But there was a message "Windows cannot be installed to Disk 0 Partition 3 (show details)" - clicking on "show details" gave me "Windows cannot be installed to this disk. The selected disk is of the GPT partition style."
What gives? I thought Windows Vista and beyond supported GPT.
The problem with MBR is that you can't have a file system larger than 2 TB.

I have an external 3TB hard drive, USB. I used a mac to partition it, 2.25TB is HFS+ (Mac OS extended - journaled) and the other is 490gb NTFS (to use on windows). It would not give me the option to use MBR (master boot record) so i used the GUID table. It works fine on macs, but windows tells me i need to reformat it. It is my understanding that most all 64bit versions of windows can read/write a GUID disk. I do not need to boot off of the drive. this is another addition to the list of "why i hate windows"

I encountered an error that stated:windows can not be installed to this disk the selected disk has an MBR partition table on EFI systems, windows can only be installed to GPT disks."

clean install to mechanical not SSD so you can use ASUS software once WIN 7 installed to merge them with the "Marvell 9128 6GB port"...Regarding BIOS funnily enough I have seen images of the UEFI BIOS in forums with all 8 ports on the deluxe in SATA configuration in advanced settings however mine only shows six (and no duplicate for UEFI like other images of UEFI i've seen"?and I have updated the UEFI BIOS to the latest version..

I wanted to resize a partition, so I backuped all important files and booted from a vista PE CD. The program used is called "Easeus". After the resizing a message appeared, which told me that the system information couldnt be updated. After a restart, it - well, it didnt restarted. I tryed to format my C:Windows partition, but Easus decided to randomly format my linux partitin, too. Yey. After that i just formated everything, so i can create one big partition so this never happens again :P. To put it in a nutshel, there is no way to boot besides from booting from a cd. The diagnostic tool of the fabricator is giving me the "error code: BIOHD-3 No bootable drives detected" message.I tried to fix it with a win7 repair disk (just realized, that the disk is for 64bit, i have a 32 bit os - i think it doesnt matter, because there isnt any os installed at all). I used pretty much every "bootrec" command, sucessful, but no change. The startup repair gave this message: "the partition table does not have a valid system partition" diskpart - act isnt helping either: "The specified partition type is not valid for this operation."I dont know if i could install any os from a disk - i dont have a bootable installation cd/dvd. Because of that i would be happy if someone can tell me where i can find a free os and how i install it. From a os i can install my win 7.

I have an older computer that is or was being used for Win XP Pro. I put a new hard drive that is partitioned with 25gb on the C drive with two other partitions of different sizes. I set the the hard drive as cable select (later tried as Master only)
Windows 7 in cable select saw all the partitions. When set to Master it only saw Partition 1 and the rest as unallocated which seems weird.
I have the boot order in Bios set as Floppy, CD Rom and then Hard Drive.
I have an external usb DVD reader for the install disc.
When i start the pc, then press to boot from CD, it sees the install disk and the install process starts. I get to the point to select where to install and I get this Notice:
"Windows can NOT be installed on to Disk 0 Partition 1"
I hit the more info button and get this notice:
"The computer hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the BIOS Menu."
It should boot to the hard drive the way I have it setup. At least it does for Win XP.
I was wondering if anyone has any suggestion as to how to get around this issue.

I'm trying to install Windows 7 Professional on a system with the 2nd hard drive partition - 100GB in size. I used Paragon Partition Manger to create the two partitions, formatting both as NTFS.
Windows XP isproperly installed on the first partition. When I try to install Windows 7 Pro on the second partition it extracts the files & installs fine right up to the point of rebooting, then gives me this error on rebooting:
File: windowssystem32winload.exe
Status: 0xc000000d
The selected entry could not be loaded because the application is missing or corrupt.
I've purchased four Win 7 Pro license keys from MS and already sucessfully loaded Windows 7 Pro on three computers with a single partition HDD, using the DVD (downloaded from digitalrivers) w/o any problems - so one would think the DVD itself is OK.
Any ideas why I can install Windows 7 Pro (using the same DVD) just fine on a single (simple) partition but get this error when trying to install on a seperate partition?

I just recently fixed my laptop a while back ago, and now I am having problems again.I was drawing on my laptop and I received an update for Flash Player. Well, I started to update and as soon as I clicked start, I went back to drawing.30 seconds later, with no warning whatsoever, My computer was closing all my programs, and restarted itself with out a prompt. However, when it did reboot, I got a message saying Invalid Partition Table.So, i was like wtf, like any person. I tried rebooting and going into safe mode. It wouldn't let me. AT ALL. The f8 function does not work. actually the only functions that do work is f2 for setup and f12 for boot options

I am running a small network at my house, and I have a Win2003 server that seems to have problems. It doesn't boot anymore. One suggestion was to take the hard disk, connect it to another computer and work on it. Ok, so I did that. Took the HD from the 2003 machine, got a connection kit for USB and connected it to my Win7/64 notbook. Of course, that blew up my notebook-When I connected the HD, the laptop froze. Obviously, I had not choice but to remove the external hard drive and reboot. The reboot now ends up in a single line: Invalid Partition Table.I have tried the system Recovery Options on the DVD, but the automatic options don't work. So I need to find another way to restore the partition table.

Im having some problems putting windows 7 on my iMac. At first, it worked fine. But i lost the reinstall disk so i made an image backup on my external hard drive. Before, i was triple booting Ubuntu, OS X, and Windows 7. I had a huge problem in windows so i restored from a backup. But now, my bootloader rEFIt keeps trying to change my mbr. whenever i try to, it makes windows unbootable. I have the MBR contents, and i noticed that it says theres 2 NTFS partitions. and when i try to install ubuntu, it wants to format the NTFS Partition and delete windows. Is there a way to fix it so i can have all three booting?

Basically while I was running Windows 7 I wanted to clone my 149GB Hard Drive to a 500GB partition on my 1TB HardDrive, with Ubuntu taking up the other 500GB.
I coulnd'nt clone using Windows tools because I always had an error of some sort. I then tried cloning using various Ubuntu tools on the Live CD - these didnt work either. I then tried dd if= of= command and it copied about 50% before an I/O error.
After the dd failed I tried booting Windows 7. The boot manager gave me 2 options. Win 7 ultimate and win 7 ultimate (recovered) win 7 ultimate never booted, because it was the new-er, half-cloned HD. The other windows loaded but was bugged, had to manually run explorer etc.

I have a Dell E6410 running 32-bit Windows 7. When I boot the machine with an USB thumb drive attached I get an Invalid Partition Table error. I hold the power button down, remove the thumb drive and then power the machine up. It then boots with no problem.

l am having a problem with installing due to a disk partition problem.. Im getting an error that says "The selected disk has an MBR partition table. On EFI systems Windows can only be installed to GPT disks".I have no clue and reading other forums it sounded like specific computers were having this problem but I built mine.Had a Windows 7 Ultimate x64 I used from a friend with no Key, Microsoft doesn't like that so I purchased a Key from them for Premium, used a W7 x32 disk by accident and I have 12 GBs of Ram so pretty inefficient.. I downloaded a W7 x64 version and am now having this problem...; First I've down this now bc Microsoft said they would send me a disk in the mail when I bought the Key but that was about 3 weeks ago and I would like to use my computer to its capabilities.

I have a OCZ Vertex.
My vertx is aligned on rules 1&2 but missaligned under rule#3

Can i use windows 7 backup tool and have them saved on DVDs, then use the windows 7 disk to format the drive (hopefully making it aligned)?
Or will the backup tool save the partition table (and the misalignet) aswell?

A few weeks ago my computer turned off unexpectedly while I was using it. When I tried to start it up again, I got a black screen with a blinking cursor. I tried going into BIOS and changing the startup order to no avail. It's now back on default. I also ran the system diagnostic and it said nothing is wrong.I got a Windows 7 repair disk and attempted to use that. I ran the startup diagonosis and restarted-- again a black screen with a blinking cursor. I restored it to an earlier point and restarted-- black screen with blinking cursor. I then attempted to restore it to other points but got an error message (0x8000ffff) each time. Finally, I tried command prompt and did "bootsect /nt60 ALL" which did nothing. So I tried "bootsect /nt52 ALL" which did nothing. I did both of those again with "/force" (which I'm now guessing was a stupid move, but I was desperate to try anything) and now when I restart I get a black screen with "Invalid partition table". When I try to go to system restore now it tells me there are no restore points.

I have purchased and downloaded both 32 bit and 64 bit Windows7 Professional (no CDs or media here only download version)
I sucessfully upgraded from Vista 32 to Windows 7 32
Then I upgraded my hard disk (140Gb 500GB) and RAM (3GB to to 4GB)
Now I would like to go from Windows 7 32bit to 64bit
When I try and run the Windows 7-P-retail-en-us.x64.exe file it upacks the box then stops with this error:"We are unable to create or save files in the folder in which this application was downloaded. Please check the folder properties to make sure that you have security permission on the folder to write flies and that that folder is not read only".
I am the System Admin and I have full rights, and have moved the exe and the setup box files to My Documentsand I have modified the directory properties/attributes but I still get the same error over and over.
I searched the posts and some people stated one needs a clean install others say you can upgrade from any version so I am trying the upgrade here especially since the upgrade from Vista 32 to Windows 7 32 was smooth and did require all the extra work of a reinstall.

I have windows 7 RC, windows vista, and linux mint running in a triple boot config. I don't really want to keep linux and was planning on installing the Retail version of Windows 7 once i buy it. However, while im booted in windows, i cannot see linux at all. I can only see the Windows 7 partition (C: ) and vista partition (D: ) under Computer.
But i can see it in Disk Management
The last two partitions are for linux.
So my question is, when i decide to install windows 7, will the windows 7 install disc see those linux partitions so i can delete them while installing Windows 7? You know the utility in the Windows 7 install disc that allows u to delete, format etc. partitions.

I have heard that windows 7 will not boot from guid disks but I remembered that Mac's can dual boot windows using 'boot camp', but macs use the guid partition map not the mbr partition map.

I installed Win 7 on a partition on the same drive as XP.
1 - XP was on C: Win 7 installed to F:
2 - I have removed XP from C:.
3 - Repaired Win 7. Win 7 boots fine.
Now I want to move Win 7 to the beginning of the drive but unsure how - as Acronis doesn't allow me to clone to the same drive - even though its another partition.
Is there any way round this?

I am using Windows 7 Home Premium N and XP Home on a dual-boot system but I want to move my Windows 7 partition from one drive to another but am not sure how to do it. Currently XP is on partition C: and Windows 7 on partition O: and essentially, what I want to do is to move partition O: to my main drive where space is already available for this to be done.
I have seven drives on my system amounting to 6.5Tb (2Tb on external drives) and currently Windows 7 is on a partition on one of the internal 1Tb drives. However, I would like to free up the space being used and place Windows 7 in a separate 50Gb partition at the end of my main drive (500Gb). Since I pre-partitioned the current Windows 7 partition before installation, I do not have the 'hidden' partition I've read so much about.
I have an old DOS version of Ghost on a boot CD and can readily back up the current Windows 7 partition ready for recovering to the prepared partition on my main drive. Once transferred I then want to delete the current Windows 7 partition. However, I know there is more to it than this! I am quite happy to reletter the partition to drive O: since I have software installed on the Windows 7 partition which is referred to in the registry.
All this I'm fairly confident about doing - but it is operations involving the boot manager that I am completely unsure of. How does the system know where the boot info is located? What points it to the right partition/drive? Does it refer to the drive and/or partition? Is there anything else I just may have overlooked? Finally, should I perhaps just leave it where it is until I'm ready to do a reinstall on the appropriate partition?
A lot of questions I'm afraid but I would appreciate some help as I'm fairly new to the question of dual-boot systems and boot management.
PS I have been looking for info on this in all sorts of places but have not so far found the answers to my questions. Sorry for any inconvenience if the info I'm looking for is already on this, or another, site. It's just that I've not found the info so far and any help being pointed in the right direction would be appreciated.

I am running Windows 7 all great and haven't had any problems, I want to make Windows 7 my sole operating system and remove my XP partition. I managed to install Windows 7 on a separate partition with no problems but just wondering if it's all fine to go ahead and delete my XP partition and then resize my Windows 7 partition back up, this wouldn't create any problems?
Just a matter of backing up all the essentials first, just in case?

I'm currently running Windows XP (SP3)and am trying to run the Windows 7 Home Premium upgrade. Each time the installation gets to the point of starting to erase the XP program files and load the Win 7 files and stops with a statement that it doesn't recognize the C partition where XP is installed. The PC has a single SATA HD with only a single partition. Is there some step that's left of the installation instructions that I could be missing?

So heres my problem: I installed Win 7 on a drive a while back and earlier today I decided that I needed more hard drive space. I saw that I had 100gb of unallocated space on the drive, but it was behind my Windows 7 partition, making it impossible to resize that partition. So I defragged with Perfect Disk 10 which moves all the files to the back of the partition, cleaned up, disabled all the usual things, ran defragger again, and then booted into a live cd of GParted. I then proceeded to move my Windows 7 partition behind the unallocated space so I could extend the volume.
Unfortunately, something went wrong and now I get the error message "Disk boot failure, please instert system disk and hit enter." So I followed the directions and ran startup repair, tried manually creating the bootmgr, and ran all the tests, but it still doesn't work. Luckily for me, I was able to reinstall Windows 7 on the unallocated space so I can at least get to the files on my other drive, which I discovered are all perfectly fine. I'm hoping this will be a quick fix since it seems like all the files are ok. What should I do so that I can boot back into that partition?
Long story short, I tried moving the partition, and something went wrong, and now I can't boot into that drive. I installed another copy of Win 7 on another partition and all the files are ok. What do I need to do to the original partition to get it to boot again?

I am having a problem that seems more like a Win XP problem, but since its part of my migration to Windows 7 and many people these days may be trying the same.
As I said, I am in the progress of migrating to Windows 7. As a transient solution until I have transferred and re-installed everything under Windows 7 I want to have a dual boot capability, i.e. I bought me a larger HD, created two partitions on it, installed Windows 7 on the first partition, and then I used a disk-imager (Acronis Disk Director) to copy my entire old XP disk 1:1 to the second partition of the new HD. I then set things up so I can choose between the two partitions using the Windows 7 boot manager. After some fiddling the choosing and booting in principle works fine.
BUT, when I try to start WinXP, I have the very strange effect, that the system at first boots and starts WinXP up fine up to the point where it presents the login screen. When I then enter my name and password my credentials at first seem to be accepted, i.e. I get a "Loading your settings..." dialog but to my dismay only seconds later that dialog always turns into "Logging off..." (???!@#@$&!) at which point the system hangs for some long period. If I wait long enough (~5 minutes) it eventually returns to the login screen again. I also tried to login as Administator but that failed as well (the error message mumbled something about no domain server to verify my id which is complete nonsense, since my XP system was never part of any domain, so there is no server in the world that could verify anything here!).
Any idea what could cause this and why can't I not log into that copied/moved 1:1 Window XP installation? Any hints/suggestions/pointers would be highly welcome!

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?

Having obtained my new 80GB Intel X-25M SSD I will of course be using it as the Windows Partition in my new installation after I receive my release copy on 22nd October.
However, I was wondering on the best way to partition the remainder of my storage to maximise performance, and particularly where I place the swap file, applications and data.
The Maxtor was the original HD that came with the PC and is approaching 4 years old. I obviously don't want to use it for anything that affects performance so the obvious usage is as a backup volume. However, I'm not sure of the wisdom of this given it is the oldest drive!
So, my current plan is as follows:Boot & Windows Partition, including application installation: All 74.5GB of the available SSD Swap File: A seperate 10GB partition of the WD drive Data: The remainder of the WD Drive (Can you get Windows 7 to move the location of the User Folders such as 'Documents', 'Downloads' etc. to a partition other than the system drive? If so how?) Backup: The Maxtor Drive Even though I am getting a full version of Win 7 by virtue of the UK Pre-Order offer, I won't be maintaining my Vista install so no need for a partition for that (good riddance!).
It is important that the swap file is not on the SSD I understand to reduce the number of write cycles and maintain its lifespan.
Does this sound like a good plan to maximise performance? Certainly using the seperate swap file seems to work very well in my RC test installation.

Would anything happen to my other partition when i format win XP to win 7 in C: drive/partition?
Okay it goes like this, I have Win XP SP3 installed with two partitions, C: and E: (<----supposed to be D: ). I intend to install Win 7 Ultimate on my computer from XP SP3 and install it in C: where the current OS is at. My question is, will my E: partition prevail still? Will the reformatting touch E:?
The reason is because there is where i want to put my backups and later migrate it.
