Windows 7 Ultimate X64 Will Not Mount Guid Partition Table Hard Disk
Sep 4, 2011
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"

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 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."
Windows 7 Ultimate 64bit
INTEL 3930K
2 x GIGABYTE HD6970
CORSAIR Dmntr 4X8/32gb DDR3/1600
WD 2TB CAVIAR BLACK 64MB/7200PRM
CORSAIR FORCE 3 120GB SSD
ASUS P9X79 DELUXE MB
CORSAIR H100 COOLER
CORSAIR HX1050W
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..

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 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 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'm planning on placing my C:Users folder on a separate partition of my HDD. I know the general scheme of things would be to create the separate parition, we'll call it D:. and then robocopy everything from C:Users to D: and delete the contents of C:Users before mounting D:Users.
Does anyone have any clue what to do if I want D: to be a FAT32 partition? Will I run into trouble because of permissions from the NTFS partition that Users originally resided on?

I bought new hp laptop.. it came with 500 GB harddisk, windows 7 home basic, I didn't get any windows cd apart from recovery in hard disk. My windows is installed in c: and that is the only drive that it have... now the situation..
1) I want to partition my harddisk without losing windows means I don't want to format C: drive
2) I also want to install linux in dual mode with windows..
Second question is related to first one because I don't need any method that may lead to situation like I can't install any other operating system.

somehow my hard disk partition became dynamic. i formatted system and insttaled windows 7 ultimate in the dynamic disk partition. from then onwards system is not booting. only black screen with cursor on the upper left corner of the black screen.
if i am not wrong windows 7 cannot boot with dynamic disk. i will have to go to the disk management and after conversion of dynamic disk to basic disk with deleting all the volumes (data). it is possible to boot with windows 7.
but system is not booting...not opening..so i cannot go to disk management.
hrad disk is showing some partitions with system reserved. except system reserved all the partitions are shwoing dynamic. and in only one partition formatting option and installing OS option is coming while i booting system with OS DVD.
reinstalltion through OS DVD is possble by booting through OS DVD. but in advanced option repartition option is not coming. the one partition in which i installed OS previously, only in that formatting option is coming. in other partition neither formating option is coming nor extend.

I am preparing a laptop for sale, and have carried out a fresh install of Windows (booting from recovery CD). During this process, I selected 'Custom installation'followed by the hard disk partition containing my personal data and 'Drive options (advanced)', followed by 'Delete'. Is this a secure method of erasure or should I take additional precautionary steps before selling?

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 brand a new Gateway NV50A with Windows 7 Professional 64 bit. I tried to partition the C Drive with 450GB to make another partition using Spotmau 2009. It displayed a window --that the system needs to restart for partioning. So I clicked on yes. After that it tried to restart and just stops on a blank Spotmau screen doing nothing(Spotmau Powersuite 2009 --Is a computer software used for partitioning and cloning). I tried to restart and bypass this window and start windows. But it doesn't work. I don't want to lose any data. I don't have a Windows 7 Installation CD.

I am confused about how much I should keep the partition in my new laptop, the reason is, I feel that disk partition do affects the system speed, I do not know whether I am correct or not. I have a 700 GB hard disk presently with Win-7 Installed, I do not know how to do the partition when windows is installed, during installation I was unable to do the partition because 'new' button was disable.I hope there is some way to do the partition after installing win-7. Please help tell the way to do the partition, also tell how many partition is optimum with what size.

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?

place Daemon Lite on a second hard drive I have created out, then mount the Recovery Disc to the program in the hard drive and run a "Reset to Factory Settings" recovery from that mount? I think it would work if i boot from bios to my clean HD and then use "cd "Gaemon" and run the ISO file from that dir.

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.
