(Accidentally) Deleted EFI Partition, can't boot.

Q: (Accidentally) Deleted EFI Partition, can't boot.

Hello,
I recently partitioned my Asus ROG G750JW into 2 main parts: One 300GB for a mackintosh, and one 6** (remaining space) for windows 8. That worked fine, until I tried to format what I thought was random partition with a size of 128MBs. I believe this to be the EFI partition, and you know what that does. I cannot boot to windows 8 or mac, and windows boot manager no longer shows up in BIOS. I have a windows 8 reinstall disk and the hackintosh install disk. When trying to refresh from the windows reinstall disk, I get an error saying that the disk is locked. What I need to know is if there is any way to restore this without erasing my hard drive. I do not have access to a windows computer (I can if I have to, but it wouldn't be ideal), but do have access to a mac. I don't have restore points, even if I did they are on the now one-huge partition, which by the way is listed as MBR format. Thanks in advance, -AJ

Preferred Solution: (Accidentally) Deleted EFI Partition, can't boot.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: (Accidentally) Deleted EFI Partition, can't boot.

Do you have something you can boot and get into a command prompt for Windows? If so, you may be able to recreate the MSR partition.

If you can, run Diskpart and list the disks and select the correct one with the install, probably disk 0. Then list the partitions and copy that listing and post it next time.

Diskpart
lis dis
sel dis 0
lis par

exit

What might be happening is you removed a partition in a sequence which changed the partition number the boot manager is looking for..but just a guess. Restoring it may or may not help the situation now... You may end up having to run a bcdboot command to reset the boot entries for Windows 8.

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 all

I am sitting here with a buddies DELL inspiron M5030. I am currently getting the "Windows failed to start" that lists "File:\boot\BDC" "status: 0xc000000F

What I don't have:

The original windows install/repair CD. It did not ship with the laptop, and he didn't make a copy. ( I know this cd would easily fix my problem )

I also only have a general idea as to the variety of the operating system: the owners tells me its windows 7 64bit but doesn't know the variety. Not sure if that matters)

What happened is

I guess while he and his friend were trying to install a "duel boot Linux Mint 13 partition" they ran into some issues with several small partitions which confused them during the install. Somehow this confusion led them to delete? format? or change the status of the most important partition on a windows machine. (they say they did not delete or format it, they said they accidently switched it to active)

The owner was having problems with slow operation before and is what led him to install a mint partition on my advice. Since I underestimated the difficulty of accomplishing the task I have volunteered to try and fix it.

questions: ( I am trying to find a fix that does not involve a 3gig download )

Are there any options short of downloading an ISO of windows 7?
can a recovery repair disk accomplish this task?
can one be downloaded?

A:A buddy accidentally deleted his boot partition. questions?

Have a look at what partitions are still there with the linux's partition manager program.

There should be a very small one (100 mb or so) at the beginning of the drive, set that to active if it isn't already, as that contains the Win7 bootloaders.
There should be another around 5 GB or less that is the recovery partition. If you are relatively lucky during POST (there is white text on blackscreen) there is a key you can press to initiate a recovery to factory conditions. If the partition with that is still there anyway.
There should be the primary partition which should be pretty big and not marked as active.

Background information

My laptop is a Toshiba Satellite L50-B with Intel Core i7 and AMD Radeon R7 M260. It came with Windows 8 pre-installed when I first bought it, but I soon wiped the disk to install Windows 7 instead. I also installed Ubuntu on a separate partition so I could dual boot. So the GRUB bootloader replaced the MBR. This isn't the issue though, just want to inform the laptop is running in CSM mode(or legacy) instead of UEFI.
*******************************************************************

First of all, before you assume, the hard drive is working perfectly. I can still boot to Windows and it works fine. More on this at the end.

Now the issue is, I removed the Ubuntu partition, and I've really no idea what I did wrong with restoring/fixing the MBR. Now, whenever I try to boot, it displays "No boot device found". I've tried:

- Windows Recovery
- Windows Recovery using disk
- Parted Magic (Hiren's BootCD)

Mainly, I tried to restore and fix the MBR using bootsect and bootrec (fixmbr, fixboot and rebuildbcd). Also automated repair using the recovery.

As I mentioned above, I don't think it's a problem with the hard drive, since I'm posting this very question from this problematic laptop, on the main Windows installation.

I can still boot into windows, but only using either:

- Windows recovery disk (without booting into the disk, just have it in

I have a 1.5TB HD of which I originally created 3 partitions of around 500GB each (C, D, and E). I have Drive C: which is my main Windows 7 Ultimate x64 partition. I had an older installation of Windows 7 Ultimate x64 residing on Drive D:. I simply use Drive E: as storage of large media like movies, software, music, or anything else and it does not have an operating system installed.

Yesterday I decided it was time to format my old Windows installation on Drive D: hoping to merge it with my storage drive E: Big mistake, because it turned out Drive D: was my system partition. When my computer tried rebooting after completing the format I got a hang while the post screen says "Loading Operating System..." indefinitely. I initially panicked and tried to re-install windows 7 with my install DVD back onto Drive D: and it still wouldn't boot.

That's when I found a few promising discussions on this forum that gave me hope; mainly starting on the third page of this following thread between user rogerfour and the always helpful gregrocker: Changing the System Partition?

As Gregrocker suggests, I downloaded and burned a bootable image of Partition Wizard. Unfortunately, my entire disk and all the partitions are listed as Dynamic Disk instead of Basic.

A:Accidentally Deleted system partition. Cannot boot. Dynamic Drives.

Dynamic disks are pretty much to be avoided at all costs. It usually happens when a user tries to make a 4th partition. A warning should come up asking if you want to convert to dynamic. The correct answer should be "no!!!!!".

Is your data backed up?

You probably have to convert dynamic back to basic. It's doable and there may be a tutorial on this forum about it--if not, there are instructions on the net if you google.

It isn't pretty and your data is at some risk if not backed up.

Are you using version 4.2 of Partition Wizard?

Greg should see this and can give you more details.

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!

Hey guys.
I made a bit of a mistake. I was deleting my XP partition on my HDD (Via the windows 7 setup) and accidentally deleted a system partition. This in turn, as you can imagine, left my computer unable to process that my windows 7 partition was a bootable partition. I installed a fresh copy of W7 on another partition, and all my data from the previous W7 installation is still there. Now my question is this (and I think I know the horrible answer, but no harm in asking); is there any way to restore the original partition to a bootable state? I tried using the W7 DVD to perform a repair, but that doesn't work since it doesn't recognise the partition as a bootable partition, only a data partition.

I just made a terrible mistake!

I've recently set up a desktop PC after 2 years without one.

Anyway, I've been backing up all my old 3.5 Inch HD's to newer and larger drives.

I just got finished moving a heap of files to a new drive, and when done, accidentally deleted the partition of the new drive and was just about to format it thinking it was the old empty drive when I realised what I had done...

So my question is, is it possible to recover a deleted partition? I'm guessing all the information is still on the drive as I haven't actually formatted it.

Any help would be much appreciated!

Never use drive letters to identify drives. They change all the time.

The drive will not show up in explorer in Windows if it has nothing to display. If it has no file system, there is nothing that Windows could show you, so it does not appear.

You may be able to recover the partition. Try recovering either the partition or your files. Move them all somewhere else if you get access to them and then repartition and reformat the drive.

Try accessing C: with another computer too to make sure it's intact.

If you still have no success, I suggest accessing C: and removing any important files and reinstall windows with ONLY that one hard drive connected to avoid the boot files from being installed on another disk.

HP/Compaq 6910p laptop running on Win XP Home. I'm a rookie and not very computer savvy, but I'll try and give a little history? I know I shouldn't have messed around with this.

But MSE couldn't remove it and I was tired of every time MSE notifying me of the virus right after restart. After reading online about Avast doing boot-time scans I decided uninstall MSE to try Avast, but no luck after several attempts. Then tried malwarebytes, but didn't even find anything. So, I read online in the link below and that's where I really screwed up. I deleted the 2mb partition like it said and then my computer wouldn't boot after restart.

So, I decided a week ago to install Ubuntu 11.04 alongside my Windows 7, which as you know, created a new parition. As you also know, Ubuntu likes to use it's own boot manager. Well, I decided that I was going to download and install the Windows 8 Build 7955 (as I found on Windows 8 Forums) onto the partition that was occupied by Ubuntu.. so, I downloaded the image and then, in my disk management, deleted the entire parition that Ubuntu was installed on. I went to restart my computer to finish an AntiVirus update shortly thereafter, and got a message saying something along the lines of "Grub error; unknown filesystem." I attempted a repair with my disc and nothing worked.

Right now, I am installing Windows 7 on the new parition in the hopes that I can get it working again, just to get at my files on the main parition. If not, I do have a SATA-to-USB adapter that I can use to manually extract the files onto another computer, and then just wide the drive entirely, but I'm really hoping I don't have to do that, as it would be SUCH a nuisance if I had to re-do EVERYTHING on my laptop. So, what I'm asking is, if the fresh install on the new partition doesn't work, is there any way to restore the original boot manager, or am I kinda dead in the water?

A:Deleted partition, now cannot boot!

Your current process will most likely solve the issue for you as the new installation should see the old installation and allow for it in the newly created bootmgr.

I used EASEUS Partition Master to delete an OEM partition which was a system recovery partition from the original Windows XP install.

I then expanded C to fill the complete drive as it is only 80GB. Those two actions ran as 1 job.

Now the system will not boot.

I tried some tips from this forum, including using the Recovery menu from the Win 7 disk, but it has not helped at all.

The disk is now listed as Disk 0 Partition 1. It has no drive letter.

If I let the Win 7 install disk run up to the part where you select the install disk it says, "Windows cannot be installed to this hard disk space. The partition was reserved by the computer's Original Equipment Manufacturer (OEM)".

I do not understand why it says that is the OEM partition, as I told EASEUS to delete the OEM partition and then expand C to fill the disk. Surely it should be the C drive now.

Have I totally screwed it up?

Is there any way I can recover my C drive and my Windows 7 install?

If you can boot in safe mode and get to system restore, that will probably work.

A:Deleted Recovery Partition and now i cannot boot

That partition was probably also the active boot partition, with just Windows (without boot files) installed on the main, inactive partition.

That partition was also the only method you had of recovering Windows to it's factory defaults - and you've blown it away.

Before doing anything potentially risky like that, you should have created a full back up image of the entire hard drive. As it is, I can't see how you are going to avoid having to purchase a new copy of Windows now.

There is just one thing that might work. Borrow a Win7 DVD and perform a repair install, using your own product key if prompted for it.

I have an HP Compaq 6910p laptop, with Windows Vista 64 bit Ultimate. It has been working perfectly.

Today I used Acronis True Image to make a complete PC backup. When I started Acronis, a pop-up asked me if I wanted to protect my laptop by letting Acronis create a secure partition to do backups in. Foolishly I pressed the button, and it created a 35GB hidden partition, cutting the C: drive down from 75GB to 40GB.

This is too small for my needs, so I tried to reverse the chamge. Acronis let me delete the partition, but it then became unallocated space. I tried various tools to increase the C: partition back to 75GB, but withoit success. Then I tried Parted Magic, a live CD, and this allowed me to grow the C: partition back to 75GB, preserving all of its data including the OS.

However now the laptop will not boot. The error message refers to the file "\windows\system32\winload.exe" which does exist, along with all the usual folders (Boot\, Windows\, Program Files\ etc.).

I notice from Parted Magic that the single partition does not seem to be called a drive letter. It is called "/dev/sda1", mounted on /media/sda1. Could this be an issue? I can't see how to assign it a letter.

I'd be grateful for any suggestions.

A:Deleted partition, now Vista won't boot

OK - I've found the solution!

In case it helps others, here is the article I found which explains that this is a normal situation after resizing a partition, and the answer is to boot from an appropriate Vista installation or recovery disc and select "Repair".

http://www.howtogeek.com/howto/windows-vista/using-gparted-to-resize-your-windows-vista-partition/

I did that, and now the laptop boots from its hard drive again.

Messing about deleting empty partitions on my Samsung Ativ 700t and I think I deleted an important partition. 

Foolishly I thought it would only need the main C: one as that said it had all the boot files and system etc so I deleted the rest - there was 6 or 7 apparently empty recovery partitions I wiped.

I have booted into my recovery USB I made which I thought would fix any probs but

Startup repair could not repair my PC
 
I went into diskpart and there is just one partition now
Partition 1.     Type primary.        Size 58GB.     Offset 929Mb
 
I have a feeling it has (or had) some new complicated setup that used extra partitions which it had no more.
 
I also realise now that it had no coa windows key externally so I can't just reinstall and also I think it used some info in other partitions so I could access Samsung software.
 
Oh dear.  Can anyone help me fix this or at least explain what it is I've messed up as I thought I only needed my main partition with boot and system files

Hi, I'm using Windows7, dual boot with Linux Ubuntu 10.04, Recently, I installed another OS (Linux Mint). Before installing this Mint, I deleted primary partition (sda1) and created entended partition from the earlier primary partition sda1. Since that, I cannot boot into my Windows7 anymore (received error message something like "no bootable device insert boot disk and press any key"), but I've no problem in booting into both Linux Ubuntu and Mint.

I've tried a few things, but seems like the luck is not with me. Below are the things that I've tried:

1. Boot Recovery Disc Windows7 and done the Repair Startup many times (more than 5 times), still no luck.

2. Boot Recovery Disc Windows7 and chose Command Prompt to use:
Bootrec /scanos - The Windows is listed.
Bootrec /fixboot - No element found,
Bootrec /fixmbr - Completed succesfully.

3. Boot Recovery Disc Windows7 and chose Command Prompt to use Diskpart, everything seems okay for the list disk, select disk, list partiton, select partion, except the "active" command. I've been prompted with something like "Virtual Disk Service Error: the specified partition type is not valid for this operation".

I've installed back grub for me to log in into Linux Ubuntu/Mint. From Linux Gparted, I can see this windows partition is flagged as boot. Currently, I've unplugged the other 320 GB hard disk and only use one 320 GB hard disk for all the OS above. I've read a few threads with similar is... Read more

So.. I was trying to get a dual boot setup of Win7 and Ubuntu where I had 1 partition for Win7, another for Ubuntu, and a third neutral partition accessible from either OS where I would house all of my data. The problem is, my computer already had 3 partitions set up: Win7, the system boot partition, and one called PQService. Because I could not find a tutorial to delete pqservice, I decided to delete my system partition, even though this seemed a little more risky (apparently it was lol.) I used this tutorial: TeraByte Unlimited Knowledge Base to copy the boot files to the windows partition and delete it. I then booted into a Live CD of Ubuntu, and used Gparted to move my win7 partition in order to get rid of the 100MB of unallocated hard drive space. I then attempted to restart my computer into Windows and i got an error saying that windows could not boot because of some recent hardware changes.
Is there anyway I could get back into windows without reinstalling it? Do I need to figure out some way to restore my System partition? Is there someway I could get windows to boot without doing either of those?
Any help would be greatly appreciated. Thanks in advance.

Yeah I really messed up here ... Ok so I went ahead and tested out Linux Mint 11. Looked good, so I wanted to install it alongside my Windows 7 for a dual-boot. When it came time to select the partition to install on, I DELETED a ~69gb partition, and created two partitions from the freed unused space, ext4 and linux-swap. I believe something was on that partition that was needed... >_> Linux Mint now works fine. But when I turn on the computer and select Win 7 from the grub loader, Windows starts up (The flag animation), but turns to Blue Screen midway and the computer reboots. I still have my partition in which Windows was installed, with WINDOWS, USERS, SYSTEM32, and all my documents. etc... but I cant boot into Windows.

Anything I can do to repair this? Or am I stuck like this forever?

bootrec /fixmbr

bootrec /fixboot

The first command executed successfully but the second command gave me an error "the volume does not contain a recognized file system"

So I was trying to install the OS into my 3TB hard drive and after finding the exact same one on sale, I bought another to set up RAID 1. I noticed in disk mgr that my partitions were all messed up (3 total - 350gb, 2.xxtb, and 6xxgb) where I was suppose to select drives to install windows to and I figured I can delete them all and merge it to create one big drive since I had UEFI BIOs and mobo was able to recognize the 3tb HDD. So i went ahead and deleted everything so i can do a fresh install and not knowing otherwise, i deleted the 100mb boot partition or whatever you call it. after my first restart, i got the bootdisk error message with the ctrl+alt+del to restart. Thinking I didnt format it correctly, I took the drive out and formatted it on another computer, now all i get is the ASUS welcome screen with the msg on the bottom to press del to enter bios. I have restarted multiple times and it seems like pressing anything is unresponsive. HOWEVER, after disconnecting the hard drives, I was able to boot from the DVD and get to the Windows 7 repair screen. The tricky part is that after I go through this process and plugged in the HDDs mid-boot, the system was not able to recognize the HDDs at all. So where do i go from here?

Restart the computer.
As soon as the BIOS is loaded begin tapping the F8 key until Advanced Boot Options appears.
Use the arrow keys to select the Repair your computer menu item.
Select US as the keyboard language settings, and then click Next.
Select the operating system you want to repair, and then click Next.

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.
