After formatting my new laptop, I deleted the manufacturer recovery partition, the 100MB partition, resized, merged, created a new Data partition, etc. However, I cannot mark my OS partition (C as Active; I can only make my Data (D partition Active. Please advise.

A:Can't mark OS partition as Active

I'm confused; your screenshot clearly shows partition C: being active.

While using a partition manager, trying to re-size the C: (system partition), it messed up every thing. Windows XP no longer boots. Checking the condition of disk with a boot disk, shows C: present but "invalid". I understand that it may be because the C: is no longer "active". In Norton Ghost 10 recovery, C: shows as "invalid".

Is there a way I can change the C: to "active" without starting Windows and with some other "boot disk"? I looked in UBCD. It shows the C: size and contents but I did not see such and option.


A:How to mark partition active when XP won't boot?

OK, with Hiren's Mini XP the C: is listed as healthy and "active". So I suppose "active is not the problem. Is it also supposed to say "system"? If yes, how do I check if it is already a system drive or not and if not how do I make it so? Thanks.

And now i'm stucked at the step : Creating partition to install mac OSX and mark it as active . I really don't know how . I opened the manage as admin and right click at the drive E ( which i wanted to install my OSX ) and i saw no "mark as active" option .
Any advices will be appreciate . Thanks

A:How can i create a new partition to mark it as active ?

hmm, you could try in a cmd running as administrator or better yet as such , in a recovery environment, diskpart.exe

list partition
select partition # (#= the partition you wish to make active)
(should return, bla bla is now active
keep in mind, the active partition is the one normally which has the boot files I believe. If you change this, you might render your system unbooatable...
(erm, not to worry as long as you have winpe or winre... hence why I say, better to do it already in sucha an environment)

I learnt here http://www.pcworld.com/article/165159/install_windows_7_from_an_external_hard_drive.html that I can Install Windows 7 from an external Harddrive in the event one doesnt have access to an optical drive as in some netbooks.
To enable me do that I have to extract the Win 7 ISO on an external harddrive which I already done that.
Now, I'am told that I have to mark the external harddrive as an 'Active Partition' from Administrative tools - Computer Management - Disk Management by right clicking and selecting 'Mark Partition as Active'.
I have tried that several times using two different computers but I find the 'Mark partition as Active' greyed out.
I formatted the hard drive and still no difference.

Any other ideas highly appreciated

I started O&O partition manager and accidentally pressed active on partition C and now I cannot boot windows...

I am using build 7600 x86 I loaded up the windows 7 iso on a usb memory and booted from it and chose repair, it said it found things to repair, i pressed ok, it rebooted but it did not help, now I chose from the repair menu to automatically search and fix, it said startup repair cannot repair this computer automatically and it want to send information about this problem, I wonder how it figured on doing that...

oh yes i started the repair again and pressed command promt and followed this guide: MBR - Restore Windows 7 Master Boot Record and the first thing it said about D being the "DVD" was wrong in my case, it was E and from then on the guide was excally like in my case and I completed the guide, rebooted and still the same message "BOOTMGR is missing Press ctrl alt del to restart"

I'm not new to these forums, they've been very helpful to me just browsing through when I have problems. I am new however to signing up. What happened to my computer is, I kept getting the BSOD, I went into safe mode, removed the most recent programs I had installed, and it stopped happening. I then proceeded to plug in my external hard drive. It was not recognizing it for some reason, so I went to disk management. It was listed there, just without a drive letter. I tried to assign it a drive letter, and it gave me an error message saying something about refreshing the list, (this is the error message I should have researched), I tried refreshing the drive list, and tried reassigning the drive letter, same message. I right clicked on the drive again, and I saw mark as active. For some stupid reason, I clicked on this. Then seeing that it didn't do anything, I thought maybe restarting the computer would maybe do the trick. Now my computer won't boot. It gets to the windows logo, and boom, restarts all over again. I tried many things like, startup repair, system restore, marking partition as active CMD, with diskpart, I also tried some of the commands in bootrec.exe. By the way, if this helps at all, my hard drive is a solid state drive, I also have a slave drive in there which does also have a copy of windows installed on it, (it was my old hard drive), I tried setting that as my primary boot and it boots into my old install of windows, before i got my...

Misread the drive label and deleted the partition on an USB external 80GB SATA drive. Nothing else has been done to the drive.

I did this when using Macrium Reflect Rescue disc.

I know I've seen mention of a program that can recover the partition table but I've not found it yet.

I tried EASUS Data Recovery Wizard but that didn't do it. I thought maybe Paragon had something but I've not had any luck so far. Any help appreciated. Thanks

Hi ad84555! Welcome to EightForums!

Try this:
Open your case, (hopefully you have a desktop PC), and carefully unplug all hard drives.
Boot to your installation media, and when you get to the following window, carefully plug in the desired hard drive then click the 'Refresh' button in the window,
then hopefully the drive will show.

Hi there
Partition wizard - seems no way to create a USB bootable media -- if your PC doesn't have a physical DVD drive even the PAID PRO version doesn't show the create bootable media option. PLEASE NO ANSWERS FOR BOOTABLE CD --- THIS MACHINE DOESN'T HAVE ONE.

Gone back to the FREE GPARTED program -- although it can take a lot longer to run when re-sizing / moving partitions.

(Another method -- a bit extreme though is to install Partition wizard on a Windows to Go system !!!)

The Partition wizard website is totally confusing too it shows a USB version but how to obtain it is unclear and the documentation is not good either.

We have three PCs connected on a network. One is dual boot with Win7 and Win10 (very recently sorted with help from Gregrocker) whilst the other two are both Win7 only with no System Reserved partition. What I want to do is to have both latter PCs with a System Reserved partition and remove the boot files from the OS partition. I know most people seem to want to go the other way but I believe there may be advantages when the time comes to remove Win7 and use Win10 only.

I've been going through the motions of creating a System Reserved partition of size around 100MB (without actually doing it - I can't use Bitlocker and I use TrueImage to backup/restore). However, it goes a bit further than just creating the partition as I have to get the boot files into it. I believe I have to mark the partition as active which would mean the OS partition would become inactive. I would then have to do three repair installs to get the boot files into the System Reserved partition.

I would appreciate it if someone would confirm this or put me right where my thinking is in error. I look forward to hearing from someone on this.

I'd be curious to know what you think the advantages to this would be "when the time comes to remove Win7 and use Win10 only".

You appear to be on the right track if you want to go through with it, although I can't recall anyone else who wanted to do this. You might investigate the EasyBCD tutorial on this site which is used to copy boot files---typically in the other direction as you mention. I'm not positive, but I'd assume it could be used to copy them in the direction you prefer.

I have an XP laptop, and usually run with a thumb drive plugged in to use for backup. For a subset of the thumb drives, but not all of them, booting comes to a halt with No bootable partiton (yes, they can't spell) in table.

I assume there's something about these particular thumb drives that's causing this. I reformatted one (FAT32) just as a wild guess, but that made no difference.

This is just a minor nuisance, as I can remove the thumb drive, boot, then plug in the thumb drive, but I am wondering why this happens and if I can fix it.

My work computer has a 128GB SSD that's just about full. I'm getting a 1TB SSD today to replace it. Is it possible to transfer the contents of the current 128GB drive to the new 1TB drive, remove the 128GB drive, and then have the 1TB drive become the new C: drive. Would I be able to boot from the 1TB drive, and could I create a single 1TB partition on that drive?

As I recall, Windows won't allow what I'm trying to do -- they want u to have to reinstall Windows instead. That of course would also require reinstallation of all my other programs, many of which would require the involvement of our IT department, and they suck. But I did find some utilities that claim they can do it (for example, https://lifehacker.com/hot-image-you...age-xml-326086 ).

A:Creating bootable image of C: drive with larger partition?

One way is to make a backup image (as in that link you gave) of the partitions needed (often this will be more than just the "C drive") to recreate the system. You can then restore the image to a different hard drive or SSD. FWIW, I use Macrium Reflect Free.

Another way, if you can install/mount both the old and new disks simultaneously, is to clone the old disk to the new.

After using either of the above methods you can resize partitions. I use the free EaseUS Partition Master, but there are many others and sometimes even Windows' Disk Management can handle the chore.

Creating a single partition on the new drive is not going to work if there are multiple partitions after the restore or clone, and may not be wise even if there is only the one partition, but that is your choice.

Hi All

I have made a bootable USB drive on my Windows 7 machine using a Windows 7 x64 ISO file (4.6GB) and Power ISO.

When I want to boot from the USB drive on my new Windows 8 x64 laptop, it does not pick up the bootable USB drice. However, I changed the Boot Mode to Legacy with UEFI as 1st option, so now it picks up the USB drive in the Boot menu

All fine, but when I want to install Windows 7 on a new formatted Partition, it tell me that it cannot install windows on a GPT Partitioned Drive.

How can I fix this? I cannot format the partition to MBR scheme, it does not give me the option, not even from diskmgmt.msc

I currently have a disc copy of windows 7 and I am currently running it as my main OS as well. I was wondering just in case my computer decides to have a few issues is there anyway I can make a data partition to store windows 7 or put it on a flash drive so that in the incident of a hardware failure I would be able to go into my bios and boot the recovery partition or boot it from a flash drive allowing me to reinstall the OS.

A:How can I make a bootable flash drive and data partition for windows 7

What do you mean "disc copy"? Do you mean you have Windows 7 install DVD or ...? If you mean you have only the Windows 7 that came with the computer, on the hard drive, then you can download a legal copy with SP1 integrated from here:

Official Windows 7 SP1 ISO from Digital River.

Make sure you get the same version you have, Home Premium, Pro or Ultimate and 32 or 64 bit. Note that Basic or Starter is not available.

I recommend using ImgBurn at 4X speed (or the slowest available) to create the DVD from the downloaded .iso file.

You can do this on any computer capable of burning a DVD.

For techies or folks who work on computers: Create Windows 7 Universal ISO With All Editions Selection On Install with ei.cfg Removal Utility.
This will fit on a 6GB flash drive or can be burned to a DVD.

The drive letter of my boot/active Win7 partition should be C:, but in my case it isn't; the boot/active partition drive letter is F.

Thanks in advance,

Nothing that I know of. My original Win 7 installation was "E" drive. I had considered things suggested but finally decided to let it be. It doesn't matter to Windows what the drive letter is, everything works regardless of the drive lettter. I later installed Windows 7 on an SSD drive, with a clean install (and the SSD drive the only drive connected during installation) and now back to the "C" drive.

So I got 2 different questions:

I realised my current boot drive is not marked as active and might be the reason why bios says its not able to boot from it when i put bios directly to boot from it. Now i have set it up so it tries to boot from some other non windows hdd and it says no bootable drives etcetc and starts to boot from this. I believe it boots from it cause its ssd drive.
So question is can i just mark the ssd (c as active and it will work or do i have to install windows again or have some other missing bootmngr problems? Wouldnt want to "fix" something thats not rly broken and i am worried about programs i have installed which can be installed for 3 different computers. (will it use one charge if installed again to this comp? Office is the one im talking about)

Second problemish issue:
When I installed windows to this new ssd i also put new mo-bo so of course i also forgot to put ahci on so my precious ssd is runnin in ide mode now. Seen some posts about this but will again say can i just change the registry and then sata to ahci in bios and it will work or do i get problems again and again have to install windows? Again office install worrying me.

Hope to get some answers and thanks for them in advance.

After researching my issue and found this closed thread - "Windows 7 won't read drive in explorer" I started my own little research to my problem.

First some basics: I am running Windows Ultimate 32 bit. I have 2 SATA Hard Drives (one with OS), 2 SATA DVD and Blu-Ray Drives and 1 IDE Hard Drive which is configured as a slave.

Second - I needed to do some hard drive trouble shooting for another computer that had a (possibly) dead IDE Hard Drive. To do this I shut down my computer, and attached the (supposedly) dead IDE Hard Drive in its place.

Now - all the trouble began.

After booting into the Bios, I noticed the supposedly dead hard drive did not register even though it was spinning. I kept booting into the OS to see if it would be recognized in any case - it was not.

I put my working IDE Hard Drive back in - after shutting down and removing the dead IDE Hard Drive.

I booted back into the BIOS and noticed my good IDE Hard Drive wasn't being recognized either. I then went into advanced Bios settings and walla - it saw my hard drive but said I needed to reboot.

After rebooting I noticed the same thing with the Bios, but this time proceeded to boot into the OS.

After signing on, I noticed my Good Hard Drive was no longer recognized in Explorer.

I went into Administrator and Computer Management and then into Disk Management.

What I saw puzzled me as over the past 25 years I never have seen this. My good hard drive was showing up as Disk 0 and showe... Read more

Go into control panel and change windows update settings

That way you have a choice what to install.
Then run windows update manually.
Check the list of updates for a drive controller driver.
It sounds like it is installing one that isn't working for you.
It would probably be under optional updates.
You should be able to select hide update an click ok
so it won't try to install it anymore.

Ok so my problem here might seem a little complex but im going to go ahead and type it all out in hopes someone can help me out. Here goes:

Ok so I have a 160 GB HDD that Win7 is installed on. I have a slave drive that's 320 GB that has Windows XP on it. (I boot from the 160 GB Win7 HDD).

I have an 80 GB laptop HDD with USB enclosure which I want to use to make a complete disc image of using the Win7 backup utility from the Control Panel. The Win7 HDD has 70 GB used on it so I have enough space on the external laptop HDD.

So this all sounds good like ok what is the problem? So here's the problem...Win7 Backup Utility automatically keeps highlighted the HDD's which need to be imaged for Windows to funtion properly (according to the backup utility). So when I click the Backup and Restore option in the Control Panel and then click Create a system image, I choose my external HDD (the 80 GB laptop HDD in USB enclosure) and I hit next. On the next screen it has the Win7 160 GB HDD and the 320 GB Windows XP HDD checked and they are greyed out so I can not click either of them. So now my total backup is going to take up alot more space than the 80 GB HDD external can hold.

Solution I tried:

I essentially decided to use my hard-drive for two different forms of Windows XP 32 and 64-bit. This was some time ago, and it ended up with the 64-bit partition (C:\) as my system partition. The 32-bit partition (E:\) was considered a logical drive, and I used it almost entirely, due to the fact that my CD Key for 64-bit will no longer work, for whatever reason.

Eventually, I decided that I needed the space from the old, unused 64-bit partition, and since both partitions had Windows installed on them, I thought it'd be no problem to just delete 64-bit and merge the remaining space with my 32-bit partition.

Unfortunately, before I got that far, I found out that my 32-bit partition no longer will boot. After reading up on it, I found out about the system partition and all that stuff that I messed up by deleting the 64-bit partition.

I've tried to use the recovery console via boot CD, but when using BootCFG, the /SCAN function doesn't recognize the 32-bit partition. I've verified that the files are still there (installed another partition with windows and checked via explorer), but even with an edited boot.ini, the Windows XP Home Edition 32-bit partition won't boot beyond the blue screen, windows logo after "Welcome".

Is there anyway to salvage and fix the partition? I'd rather avoid losing all the driver installations and registry keys I have on the other partition, and would much rather just make that drive the system partition... Read more

A:Multiboot, Accidentally deleted System Partition. Cannot boot other partition

Oh. Also, when in Windows Setup, the 32-bit partition in question can be seen, and is stated as "in a format not suitable to Windows Installation" or similar. I can enter it in Recovery Console, but it does not recognize that Windows is installed on it. Partition table?

Hello, I was really hoping somebody could help us. It's a bit of a strange situation we're in but I'll try to keep the facts as concise as possible.

Computer running Windows 7 Ultimate x64, 1TB Hard Drive.

Yesterday my boyfriend discovered an 'extra' partition on his computer. He'd never seen it before and was very much enthused at having the extra space to store files etc, but sadly didn't question what, how or why this showed up randomly.

Skip to today... he went to access some of the files he put on the mystery drive, but discovered the whole thing wasn't there anymore. Cue a lot of swearing, trying to figure out what happened. We've collectively been trying to find out what might have happened for the entire day and haven't got too far.

The only idea I've struck upon is that maybe for some reason the System Reserved partition became visible and/or active for a short period of time - eg. enough time for him to start loading files into that area, but then hidden itself again? Is this even a possible or plausible idea?

If this is the case, how the heck do we get the partition to show up again and access the 'lost' data... the partition obviously isn't showing up anymore and for the life of us, we can't get it to show up using partition recovery tools either >_<

Sorry for sounding totally 'noobish' - any thoughts, suggestions or ideas would be really great.

Normally you use diskpart command to mark it "Inactive". However, you have to be sure it's not the partition Windows boot from. Show us the screen shot of Disk Management then we can help you.

How do I make the second partition, which includes all files from another hard drive, pretend that it is the main partition? I want to simulate the second partition being my main one for a while.


How do I resize system partitions?

I am in deep trouble...

A while ago I made a hard drive image with Drive Snapshot (http://www.drivesnapshot.de/en/). A few days ago my hard drive crashed and I certainly want to restore it. Although, I can't afford waiting for a new hard drive, and I want to restore it to another computer instead. My goal is to be able to boot into the old system with all programs and settings intact!

- A stationary computer where the hard-drive snapshot resides (300 gb)
- A crashed laptop computer (38,7 gb)
- A target stationary computer with two partitions: (system c: 38,8 gb, d: 38,6 gb)

The problem is I cannot restore the 38,7 gb image file to the d: partition as it is 0,1 gb too small!!

I cannot use the 300 gb computer, and I cannot afford to delete the system partition of the target computer! I see only two options:
1. Resizing the partitions on target computer
2. Mounting the snapshot-image as a virtual drive (done), and copy all files but the movie-files etc to D:

Problems encountered:
1. This is impossible as the C: is the system partition and they cannot be made smaller with programs like Acronis PartitionExpert...
2. Although all files but the movies are copyed, I cannot make it boot!

A:How to make second partition bootable / restore hd image when partition is too small?

I read all the messages about making sure the partition is botable. However nothing was mentioned about changing a partition that has an existing OS working on it from not bootable to bootable.
I have two HDD with two partitions each. One HDD has Windows 98 on partition 1 and storage on partition 2. The other drive has Windows 2000 Pro on partition 1 and Windows XP Home on partition 2.
When I set up my partitions with Western Digital's Data Lifeguard Tools, the only partition that was made bootable was the one active partition with Windows 98. The other three partitions are primary but non-bootable.
I use the Windows loader to access each OS.
Now I need to format the Windows 98 partition but can't take a chance of wiping out the MBR which is on the first disk and thereby having no way to access Windows XP for regular operations until I get 98 working again.

So does anyone knowif it's possible to change the status of a working partition (Windows XP) from non-bootable to bootable without destroying the partition? Other wise I have to completely clean both drives and start over from scratch installing all the OS.

I accidentally marked a partition on a drive as active (It was 4AM and I was sleepy lol) and now I can't do a backup of my system because the disk that was accidentally marked as active is too large. I tried going into the CMD and:
Select disk 2
Disk 2 selected
select partition 1
Partition 1 selected
The disk is not a fixed MBR disk.
The INACTIVE command can only be used on fixed MBR disks.
Well according to disk management, it IS active, and trying to do a backup it's trying to include that 3TB drive as well. Is there something else I can try?

A:Can't mark partition as inactive

You probably need a portable, usb-or-DVD bootable, Acronis Disk Director or anything similar in power, ADD costs, so maybe EaseUS, AOMEI, or others may have something that can do the job.  I know that you will mark the correct partition Active later on.

I was dual booting my system with xp & Fedora. I had a need to get the Fedora space back to the windows. For that I format the linux partitions successfully & I have created NTFS partition on that space.
Before formatting, the linux partition could be observed(not read) has a partition named as "Local Disk" with a drive letter. After formatting I tried to assign the same drive letter to the NTFS, but it said the drive letter is in use. So now I have a different drive letter assigned to that partition.
Everything is fine though. The problem is that in the "My Computer" window I can still see the "Local Disk" partition containing the same drive letter, but additionally with a big red question mark(probably indicating that the partition is unavailable). As far as this remains I can't create a partition with that particular drive letter. Anyway this isn't a big issue for the OS's functionality, it looks like an ugly piece of icon. I want to get rid of this. I think this is something related to a mount point. Anybody encountered smilar issue?

So last night i accidentally made my c:/ active instead of Disk 1 or 0 (Which i understand allows it to boot up?)

And i've tried to boot up with a Usb using partition wizard, Didn't register.

THERE IS NO BIOS SCREEN. As well for some reason and if there was, i've tried spamming f2,f4,f8 and delete it just goes to the error.

Any help?

My Dell XPS 8700 desktop has 2 disk drives, a 256 GB SSD and a 2TB internal hard drive.  I'm running Win7 Pro which boots from the SSD.  In March, something happened and I didn't notice it until now.  Whatever happened didn't effect the computer's performance so far as I could notice.  I'm getting a new computer and want to repartition the hard drive on this one which would involve eliminating the 'Stuff' partition (S:).  But I can't as it is now the System partition (see screen cap).
Anyway, what happened is an active partition was established on the hard drive in the 'Stuff' (S:) partition and that was also made the System partition.  Prior to March, the SSD's RECOVERY partition was the System partition.  Both partitions have the full complement of boot files and both are designated as 'Active' which I didn't think could happen (unless the rule is only 1 'active' partition per drive, not per operating system).  What I want to do is move the 'System' designation back to the SSD/RECOVERY partition.  I found a video on YouTube that gave me some BCD commands but that didn't work.  It did no harm, it just didn't change anything.  The attached screen cap shows what appears on the Disk Management screen.
I do image weekly.  Unfortunately, I only keep the past 7 weeks so I can't go back to before mid-March which is the date showing on all the boot files on the S: partition.

Hi Folks, I have contrived to get two active partitions on my PC! After a 2 week old hard drive (D: & F -) died I replaced (now F & G) it with an old drive that had previously been configured with XP and as a boot drive. I don’t think it is acting as boot as drive C: has an active partition and boot and largely the computer runs fine with the exception of G not being search / index able? And there being a phantom path in the backup which I can’t reset. So the question!
How do I remove the active setting on G: (it holds all the variable windows data) and will it lose all the data?
Im at that point where a little knowledge is dangerous and have seen some genius replies so thought I would ask and see if you could help me out.

See attached screen shot

NB The old drive partitions were formatted before being repopulated

A:How to change active partition without removing data from partition?

Hello and welcome to the forums MarkRocketman!

You can easily change the active/inactive flag on a partition easily by following these steps:-

Removing the Active Flag from a Partition
(on a drive that's not currenly being used as a boot drive)

First, open an elevated command prompt in Windows:-

1. Click Start Orb
2. In search box, type cmd
3. Right-click on cmd.exe, and choose 'Run as Administrator'

In the elevated command prompt type in the following commands:-

SELECT DISK n (where n is the number of the HDD in question)
SELECT PARTITION n (where n is the number of the Partition that holds G)
Hope that helps!

EDIT:- As a supplementary addition here's how change it back to active:-

SELECT PARTITION n (where n is the number of the Partition you want to activate)
Exit (to exit Diskpart)

Current Master Drive (C : OCZ-VERT EX2 SCSI (my SATA Drive) - 60 GB
Current Slave Drive (D : WDC WD10EARS-00Y5B1 ATA - 1 TB

My computer used to have a boot file set on my slave drive, but OS installed on my
master. So i eventually reformatted it so that my boot AND OS was installed on my SATA (master) drive.
Recently a USB gave a conflict to my boot priority and wasn't letting me boot with both my hard drives intact. Solved it by loading start up repair via a win7 disk and "repaired" it.
However, now there's the partition of my slave drive, that is marked as system, active now. Before it was just "unallocated space". How can I "shift" that over so that nothing "boot worthy" or "system active" is part of my slave drive?

Thank you for your time. Please take a look below at the screen shot.

A:System reserved partition (system, active) on Slave drive

Disk management (right click on My Computer, Manage, Disk Management) should allow you to simply delete that partition if you don't need it. Just make sure you don't need it before doing so. I'd unplug the slave from the mobo and boot the computer to make sure everything is fine without it.

I was trying to install a software and i got this message from the software:

Thanks for any advice.

A:Your Active Partition and System Partition are residing in two different hdd !.

FWIW:  The active partition...there can be an active partition on each hard drive and the only reason for making a partition is so that it can be the boot drive or host an operating system.  If you remove the O/S, the partition will continue to be active...to no purpose.  I've seen this on my own dual-boot  systems.  By definition...any multiboot system can reflect multiple drives with an active partition.
But...Win 7 is a little different from XP regarding this designation, I don't recall that XP has/had a tool for making a partition active...actually, I didn't know that Win 7 has such a tool.  Maybe it's done automatically when installing Windows but I don't ever recall using a specific Windows function to make a partition active.
See http://windows.microsoft.com/en-us/windows/mark-partition-active#1TC=windows-7 for MS explanation.
"Don't mark a partition as active if it doesn't contain the loader for an operating system. Doing so will cause your computer to stop working."
Seems to me that your situation stems from the fact that you only have one install of Windows...and you have an active partition on a drive not reflecting the O/S.
Seems that you can easily fix that, using the MS documentation.
Then...retry your install of whatever program.

Hello everyone!

I had a dual boot on my laptop (running windows 7 and arch linux). I decided to get rid of the linux partitions and accidentally deleted the EFI partition. As a result, my laptop now doesn't recognize that there is any operating system on the computer.

What I have tried: I am currently using this: http://www.eightforums.com/general-support/52515-windows-8-cant-start-due-missing-efi-partition.html and the post by Genet with Option 3 since I allocated the space back to my disk C. I am running into an error part way thru the solution though where after I do "create partition efi size=260", it comes back with "MSR and EFI partitions are only supported on GPT disks. Convert the selected disk to GPT and try again". I don't know if I want to do that because its my local disk C...don't want to mess that up and change the format of that.

Any help will be greatly appreciated! Thank you!
