Unable To Install Windows 8.1 RTM - Selected Disk Has MBR Partition Table
Sep 7, 2013
I previously had Windows 8 installed on my desktop - I've just booted to Windows 8.1 Pro Setup so I can install it on my desktop - I've formatted my hard drive from within the setup but when I try to install Windows 8.1 Pro on the partition, I get the following error message:-
'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'
What can I do now as I don't have a version of windows installed anymore...

i brought an HP Pavilion G6 and it comes with an GUID partition table (GPT), EFI and Secure Boot. However i need an MBR partition table, so i tried disk managerment but the option "convert to mbr" is greyed out and when i run the "diskpart - list disk - select disk 0 - convert mbr" i get an error "cannot convert a partition which has a pagefile on it" (disabling the pagefile didn t worked).
I guess my only other option is to format it, but the notepad comes with an lincesed Windows 8 which i dont wont to loose. So what are my options? I dont ave the CDs, as it s HP packet.
Update:I ve successfully formatted my Notebook. All i had to do is enter legacy mode, disable secure boot and boot from the Windows 7 DVD. So if you ave no intention using Win 8 it won t be a problem to "downgrade" in an UEFI/EFI System.

I have a laptop with Windows 8 installed in a 256Gb SSD. There's a 32Gb recovery partition whose purpose is to recover the drive to factory install. Since I already imaged this recovery partition to an external drive I would like to delete it and merge it to the main C partition to increase capacity. I know I can do this easily with 3rd party solutions (Easus, etc), but I'd like to do it using the Windows 8 built in Disk Management. I tried but when I right click on the 32Gb recovery partition the only option that shows up is "Help", it does not show any other option that shows for the other partitions (Shrink, etc).

I recently tried installing Ubuntu dual boot with my Windows installation as I had done with a previous system. I somehow failed to notice I had whole disk selected rather than the option for partition. Well. Obviously it wiped my whole disk along with my Windows 8 installation. I aborted the Ubuntu install progress right away and shut down, of course it was too late to save everything.
I resorted to Testdisk. It was able to find my C: (windows) and M: partitions, which I am able to restore in order to copy and access my data, but not simultaneously. It must be only C: (Acer) or M: at a time.
At this point my data is safe. My only concern now is fixing the Windows installation, I had neglected to create a recovery drive until after this headache transpired, and that was done with my friends Dell machine. I do not have any Windows 8 discs or drives, nor do I know how to aquire it without purchasing, which is not an option.
I suppose I'd like to know if I'm going to be able to boot Windows again, using testdisk to restore the proper partition table setup and (I don't need M:, it's been backed up)
I cannot restore or refresh the system via the recovery Usb created on the other pc as it reports the drive is locked.
Laptop is an Aspire V5-552p-x440.
I cannot access Acer Recovery.

After installing Windows 8 my computer had four partitions; I thought they'd be fine but want to change it to have two big ones, one for Media and one for typical C: usage. I moved everything out of D: to delete the volume so I would have free space to the right of C:, which I've read is what you need to do in order to extend partitions using Disk Management. However, the option is still greyed-out when right-clicking C: as shown:
I did this because I've read mixed things about using 3rd-party software to extend partitions; some that don't truly extend it and just trick your computer into merging the two... I like doing things the purest way possible and would like to truly combine C: with the free space to the right of it. Why the option is not available?

I am trying to do a clean install of windows 8 on my laptop (Elitebook 8770W) from a USB stick with original MS Windows OEM iso. Once I boot from usb stick, at the setup screen I enter the product key and then choose advanced to do a clean install. I then choose my hard disk partition to install windows but I get stuck here with this error:
"Windows cannot be installed to disk 0 partition 1"
I deleted the partition and choose to install on the unallocated space (150GIG) But still get the same error and when I click on the error this is what I get:
"Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's Bios"
In bios I have my disk set as Raid and I also have a m-sata Flash cache. If I change raid to AHCI I will be able then to install windows. But if I turn it back to raid after install I will no longer be able to boot I have to be in raid mode to use my m-sat as cache drive.
So here I am stuck not being able to install windows I even downloaded latest intel rapid storage technology drivers and put them on the usb stick with windows setup files. When i got the error I choose to load driver. But even after that I was getting same error and windows would not install on my HDD.
What's the right way to install in this condition (raid)?

I accidentally deleted the EFI partition, required to boot into my Win 8.1 installation - unbeknownst to me that EFI partition was on a different disk to where my Windows is located. To complicate matters the Windows install is on a RAID0 array.
Windows repair using the original install media didn't work.
EasyRE didn't detect the RAID0 drive.I saw various instructions on how to reconstruct the EFI partition, but they all assumed that the EFI partition is still there, which in my case it isn't.how I can get my data off that drive and re-install Windows?

Basically I installed windows 8 on an SSD and partitioned one of my 2tb drives in order to install / transfers programs and documents etc into windows 8 from the old windows 7 install. This worked perfectly, however, windows is not not letting my format the windows 7 side of the partition so i can expand and let windows 8 have the full 2tb of storage!
Windows 7 is installed on E:, I think perhaps the bootmgr may lay inside of E hence why I can't format it.

I am trying to build a recovery drive on a USB flash drive for Win 8.1. I have been unable to copy the Recovery Partition from the PC to the recovery drive. It appears to be disabled when I view it from the Recovery Drive. I have discovered that in Windows 8.1 the recovery partition is installed in a INSTALL.WIM file format. How do I locate the Windows 8.1 INSTALL.WIM file and how can I register the INSTALL.WIM file as the Recovery Image on my PC?
I downloaded the Windows 8.1 Enterprise evaluation kit and became totally lost.

I have bought a new PC/Server to be used as a media server, I have 2 x 2TB disks installed which I believe I have mirrored.
See below screenshot.
From the reading and research I have done I don't believe if one disk was to fail the other one would work, I think I may need to mirror the EFI system Partition and Recovery Partition of which I'm not too sure how to do this?

I need to create a partition on my PC and I've followed tutorials but I always run into the same problem: Right clicking a volume in disk management only gives me a "help" option. I've connected external storage and it gives me the menu shown in the tutorials/how-tos.
Is there something I'm missing? I've followed all the steps to the letter, save for the ones that are not possible on my PC (shrink volume/etc)
Additional info: PC is an Acer Aspire V3-551 laptop
The HD was replaced a few months ago and the original OS updated to 8.1 from 8

I recently shrank my had drive and made a data partition. I then did a factory restore and installed windows on the c partition. Everything seemed to go well. I now can not see the D partition. It only shows up in Computer Management. It will not allow me to do anything with it. It is calling it OEM partition. What do I need to do to recover this?

My Toshiba Satellite Laptop has Windows 8. For some reason windows 8 wont load. It gets to the screen where you select which username you want. But from there its non responsive, I cant get into Windows, I cant restart to load it up in safe mode.
I got a Windows 8 disk which I had to change the bios to load it up. The cd loads but it says the automatic repair wont repair the laptop. I try to refresh windows 8 but I get a message saying the drive where windows is installed is locked. unlock the drive and try again. It also wont let me use system restore.
I try to use the reset pc option but I get a message saying unable to reset your pc, a required drive partition is missing.
At the start it gives me the option to install windows 8, I don't know whether to just do that? Is it ok to do with windows 8 already installed?

I wanted to set up dual boot for Windows 8. I created a partition with enough space to load windows 8 from an ISO file.
However, after creating the bew volume, windows 8 displays a message that the partition is dynamically loaded. I have deleted the partition and re-created it with the same result.
I don't remember seeing an option for dynamic creation.
In a previous attempt< I have a partition(Q), which cannot be deleted, don't know if this is a problem.

I recently purchased an Asus X551 laptop with Windows 8 but straight the way uninstalled Windows 8 and installed Ubuntu (after creating a Windows 8 recovery drive just in case). I have since decided that I want Windows 8 back as I have found that I cannot use a lot of software on Linux. The laptop did not come with any form of recovery disk or installation disk, the only reminent of Windows 8 I have is the recovery USB that I created from within the OS.
When I plug in the USB and boot from it it brings up the recovery menu with options to reset the PC but when I click it it says something like - "Unable to reset PC. A required partition is missing".

I'm evaluating a windows 8 gateway. it is unable to boot. automatic repair doesn't work, no go on refresh, there is no media for re-install. no restore points. just to see, I am checking out what diskpart says. disk 0 online, size-0, free-o bytes. the pc had been dropped. I reseated the hard drive to rule that out. is this drive dead? disk 1 is 14gb, but I'm thinking that the 16 gb flash drive that is plugged into it.

I am unable to move my boot data to another partition. Please have a look at the following picture-:
As you can see I have created a separate a partition before my C drive and formatted it.
I have used the following command to copy the boot data from my C drive to the System partition(S:)
bcdboot C:Windows /s S: /f BIOS
But as you can see C drive is still marked as "System" which means my PC isn't actually booting from drive S:.
How do I force my system to boot from drive S: and not drive C: ???

I want to join my D and E after that I want to re partion 90 GB's 3 additional partition.

I have a Windows 8 system on a SSD with about 200gb free on the left of the C: partition (left over from previous OS I dual booted). The ssd is gpt partitioned and boots using EFI.
I tried moving the partition to the left using Gparted which worked but windows wouldnt boot. I tried recreating the bcd files with no success. After doing some research I was lead to believe it was due to keys under HKLMSystemMountedDevices having the partition offset hardcoded as it would start to boot windows then crash with an error saying boot device inaccessible.
I got it booting again by moving the partition back to the correct position and recreating the bcd files again.
So are there any guides or tools that can move the partition to the left and update the relevant areas of windows so that it can boot? Or extend the partition to the left without breaking it?

I've long been an XP user, just purchased a new desktop with 8.1 and a 2TB HDD this week.
I was partitioning some drives to organize things, and i am stuck.
On a 2TB drive, i have so far allocated 900GB over 4 drives for files, etc. [100,200,300,300]
I have 946.42GB left on my C, and i was hoping to get at least 2-3 more 200/300GB drives before leaving the remainder to C, but when i attempt to shrink my C drive, Disk Management tells me ive only got 20835MB/20GB available space to shrink. Wtf? I have literally added nothing to the computer except uTorrent, ive used Disk Optimizer to defrag the C drive 3 times, and still all of this space is unavailable? The OS has unmovable files scattered that loosely??

Either with my startup today, or sometime in the last day or two, all my drives/partitions in Windows Explorer (and XYplorer) have lost their labels and are now showing as "Local Disk." Looking in Windows 8 Computer Management and EaseUs Partition Manager, the labels are there, as shown in the screenshot. I ran all three main repair modules of Yamicsoft Windows 8 Manager and there have been a few reboots, but still the same.

I would like to know how to install Windows 8 from a hard drive partition, so that is much faster than installing from a USB ... I've seen guides on how to do, how bad MBR, and I want to know how install W8 from a partition GPT / UEFI.

I want to partition my C Drive to install Ubuntu 14.04 so I can dual-boot with Windows 8.1. When I tried to shrink the volume it wouldn't let me got higher than 4GB even though its a 500GB drive and I have over 259GB free. From looking at it the drive seems to have a few recovery partitions one being just under 24GB. Does the number of drive partitions factor into the amount of space I can give to a partition. Also if the recovery partitions are factoring into this can I move them to another drive or just outright delete them.
