Windows 7 Install On EFI System And GPI Disks
May 16, 2011
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 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?

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.

I am going to build a gaming rig in the future when i have the money to, but windows 7 install disks are very expencive, but i already have a laptop with windows 7 AND all my programs. it constantly prompts me to make restore disks (then when i click yes without haveing a dvd in the tray it still starts the proses for some reason) so, if i got it to function properly and i made my 2 restore disks (it said it would take 2 disks for complete burn) could i use them to instal windows and my programs onto the new computer? would save me 130 or so dollars (if i could get it to work right) so it would be great if someone could confirm this.

On Friday I attempted to install windows 7 ultimate x64 My existing machine is a XP Pro SP3 machine and it meets the system requirements as per Windows 7 upgrade advisor I booted from DVD and followed the steps up to selecting where to installl windows 7
This list showed me
Disk 0 Partition 1
Disk 1 Partition 1
Disk 1 Partition 2
Disk 0 is my C drive where my windows xp is installed - 300GB disk Disk 1 is where is store my files: pictures, music, documents etc - 500GB disk Partition 2 of Disk 1 is unallocated 9GB I selected Disk 0 Partition 1 Then selected Disk Options Format Drive Clicked Ok to the message about destroying data And allowed the install to proceed What i intended / expected to happen was that windows 7 ultimate would be installed on drive C: (Disk 0) and that drive D: (Disk 1) would remain intact and untouched by the process The Windows 7 install completed successfully I logged on to my user account, activated my windows 7 copy I then looked at my disks and what i see is that: Drive C was formatted and windows 7 was installed there BUT The install process formatted drive D and copied the windows XP installation to that drive So i have lost a lot of data that i did not expect to, and, of course, had not backed up in ages. For now, anyway, thats beside the point.I then removed the windows 7 DVD from the drive and rebooted the PC When the disk was removed the machine booted to Windows XP - running from the copy taken earlier on Drive D However, when i replaced the DVD to try to boot to windows 7 again, it began the installation process from the start?I dont remember selecting a dual boot option during the initial install, but maybe the steps i took led me to something like that by some default?

I have an OEM version of Win 7 Pro (English) currently installed on my system. I am currently upgrading my Motherboard and CPU, building another system with the old parts. As the recipients of my old setup are German, the OS needs to be in German for them also.
Here is my dilemma. When I pickup a new copy of Win 7 it will be in German (as I am living in Germany). They need a German instillation of 7 and my current OEM key is locked to the old motherboard. Will I be able to use that English OEM key with a German instillation, then use the new German key with my current English disks?

NT Kernel & System rises to top of list in task manager and then just totally stops installs from proceeding. I have fought NT Kernel & System on 3 computers running Win 7 x64 ever since Win 7 has been out. No one yet that I know of has been able to solve the issue. I now need to install Java and can't because of NT Kernel & System stops it. I have tried everything on every forum and sites l find with Google searches. Nothing has worked yet.

Is there a repair with these disks? I am getting a BOOTMGR missing but I checked the hard drive and it is fine. I do not want to lose anything because I have a lot on it.I cloned my image about 5 days ago and I may go that route, however, I have done things since then and don't want to lose the data. Before I load the HP Recovery disks (4 of them, and I had to order them for free except pay for shipping), is there a repair option?

I was given a Pavilion DV9000z by my sister who had purchased a replacement for herself. She wiped the two installed hard drives and clean installed windows 7. It appears that there is a 100MB systemm reserved partiion on one disk (total size 320GB, the rest of which was unpartitioned when I got it), and the operating system was loaded on the second disk (120 GB).I had a dead Vista laptop which had a 100GB SATA drive. I wanted to reformat it to have as a sppare. If I pull either one of the original drives out it won't boot. If I take out the 320 GB drive (with the 100MB partition) the laptop either goes black screen (if I move the 120 GB drive into the primary bay) or tries to boot Vista (if I put the scavanged hard drive in the primary bay), or tells me operating system files are lost (if I pull the 120 GB drive and replace it with the scavanged drive).So it appears to me that the 100MB partition on the 320 GB drive is waht the system is booting from, but that it won't load Windows 7 unless the second drive is also there.Is there any way to move the system reserved partition to the 120 GB drive? Or the operating system files to the 320 GB drive? It scares me that if either drive dies, the system won't boot.

Almost every Windows application that tries to deal with my new Blu-Ray drive via a Windows dialogue insists on trying to format the BD-R disk first.
You can't format a BD-R disk, it's write-once and formatting would effectively destroy the disk, at $4 a pop.
BD-R disks don't need formatting, those applications that can handle them properly and independently do just fine without formatting.
If I tell it "no, don't format the thing", then Windows insists there's no disk in the drive.
How can I tell Windows 7/64 SP1 to quit trying to format BD-R disks, and recognize them correctly?

My computer has two 1GB HDDs.Disk C: is the boot disk and is running Windows 7 64 bit upgraded from Vista 64.Can I use the same Win 7 disk (and key) to install to Drive E: as a clean install? I think the new installation would pickup a dual boot system and give me the option as to which I wanted to use.I understand that I can't use the same disk for two different machines.But can I use it for two installations on the same machine?

So, I recently bought a used computer from CL. The machine is a Dell Laptop that originally had Windows Vista installed on it. The original owner upgraded to Windows 7 Enterprise and had a bunch of new software installed on the machine. (FL Studio, Photoshop, etc.)I was able to use the computer successfully for the first day until I installed iTunes. Something went wrong, and now when I boot up in normal mode Windows will freeze as soon as i try to open anything. I can open the Start menu, but anything past that will cause a freeze. The computer works fine in all Safe ModesSo, what I would like to do is restore Windows 7 to it's original configurations and still be able to keep all those great programs already installed. However, I do not any of the Windows 7 media that was used for the upgrade. What can I do? Will creating a system image work, or will I end up just copying the freeze problem if I do that?

I am looking at reformatting my computer, the only thing holding me back is a matter of software. I have a windows 7 professional 64-bit disk which came under the OEM licence, and I purchased Microsoft office 2010 on-line (I have an installer and a disk I had shipped to me). Would reformatting my computer and reinstalling windows require me to use one of my uses of either of the mentioned pieces of software? And where could I find how many uses I have (if it is indeed limited).

My rather new Acer Predator G has been acting up lately. I tried a restore point but this doesn't seem to help. As a last resort I was going to format the disk and re-install 7, however Acer never sent me recovery disks and I don't have 7 disks (Came pre-loaded). So my question is, if I can find someone with windows 7 disks can I use them + The CD key that's on the label of my desktop? Or do I need specific ones? Acer will send me recovery disks for 20$ but If I can pull this off for cheaper, I'd like to.

If a pc was upgraded to Windows 7 from Vista, and we want downgrade Win7 back to Vista, can we use the original Recovery disks (from the Vista OS) to do this? I know Windows 7 is a better OS, but this is due to software incompatibility issues.

When trying to backup to removable media ( CD or DVD ) Windows tries to format blank disks. I believe this will not work, look at the following link. Windows Backup does not back up to CD-R, CD-RW, or DVD-R devices It would appear this type of medium is not supported.

I have a 2 year old Gateway laptop (NV5929u) i5 430M w/ 4GB. It came with Windows 7 Home Premium 64-bit installed. The computer crashed with a blue screen a few months ago, and I could not locate the recovery disks, so I ordered a set from Gateway (1 System disk, 2 Recovery disks, 1 Language disk). My attempts at recovery were unsuccessful and I got the msg: failure disk 0 partition 3. I replaced the HD with a brand new one yesterday. My attempts at recovery went a bit further, to the point that the computer loads the information on the various disks, but when it tries to restart.
