Preferred Solution: EFI / UEFI partition Deleted

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.)

Hello all.

I am running Windows 8.1 on my Acer Aspire V5-571PG. Well, Windows 8.1 may be a stretch.

Months ago, I decided to switch to a dual-boot configuration of Windows 8.1 and ubuntu. To accomplish this, I switched my bootloader from UEFI to GRUB. I decided ubuntu was not for me, and rather than looking up uninstallation techniques, I simply removed the ubuntu partition and used a third-party tool to reallocate the empty space to my Windows partition (I somehow managed to create my ubuntu volume to the left of the Windows volume so that was a complete pain). Now I am stuck with a GRUB startup scheme, displayed in pictures below:
Above is the first screen. I figured out that to navigate to the next menu, I have to type "exit." After I first type "exit" and hit enter, the same screen comes up. I repeat the process and the next screen is shown:
When I select "Windows Boot Manager," I am able to successfully boot Windows 8.1.

I also checked my disk partition settings and I infer that I have also mistakenly deleted my recovery volume:

Any help and direction in repairing my disaster of a bootloader would be much appreciated!!!

Go into the BIOS and under Boot Options delete the Ubuntu as a boot source. Then move the Windows Boot Loader up in the boot order to boot first. This has worked for me.

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

Is there an easy / standard way to repair the EFI partition on a Lenovo G580? While attempting to boot to EFI by anymeans, the machine is just cycling on to Windows and ignoring the request.  E.G. From Windows, shift-restart is correctly offering the recover options / advanced boot options, but when I pick UEFI, it just cycles back to Windows. I can't usethe diagnosics disk because EFI is set to secure boot and, being unable to access the BIOS, I can't turn it off.

I've downloaded Windows 7 and made a bootable USB drive. I installed Windows on a couple of PC's and my HP laptop. I've noted that when installing on laptop, I've had some issues. In BIOS settings, the boot mode was selected to UEFI and no matter the boot sequence, it just wouldn't boot from USB (note: there was a USB Hard Drive and a USB Generic Volume option and I've checked the 'boot from USB device option' above). I've solved the problem by switching to Legacy boot. It booted from USB with no problems and Windows got installed correctly. I've done the same thing on an another HP laptop, (same thing, UEFI wouldn't boot from USB, while Legacy would) only this time to see that all of the partitions are formatted as GPT and I get a message saying that Windows can't be installed on a GPT partition. I am presuming that this is due to the legacy boot mode (my overall knowledge is very low, so if any of this doesn't make sense please forgive me).

I am trying to create an autounattend file to install Windows 10 as a UEFI install. I am encountering one problem when it comes to creating the partitions in the unattend file. Windows 10 creates 4 partitions, 3 of which (MSR, EFI and OS partitions) I have no trouble with as they are roughly the same as Windows 8.1 just different sizes but the new 4th partition, a 450MB "Recovery" partition, I can't seem to create.

When installing Windows 10 it lists the partition type as "Recovery" but using WADK there is no option to set "Recovery" as the partition type, the only options are EFI, MSR, Extend, Logical or Primary.

Can anyone tell me the exact attributes/settings required to create the new 450MB "Recovery" partition in an unattend answer file?

My searches on the web so far have not turned up any helpful information regarding this new partition created by Windows 10 so hopefully someone here can help me.

As far as I know, the recovery partition is just a normal primary partition.

Why are you setting any up - the install package does it all for you ie just delete all existing partitions and let it do its own work?

Hello,
 
I have a HP envy x2 which has no uefi partition and at the moment it seems that it's impossible to reinstall this computer. I have tried external dvd-rom and bootable usb, but they aren't recognized when I turn on the computer. At the moment the computers has no OS.
 
On hp forums I read that you must turn on legacy boot in order to be able to boot from cd-rom, but there is no such option, there isn't even a boot priority option, only uefi boot priority which is greyed out at the moment, probably due to absence of uefi partition.
 
I have never seen such basic bios with so few options, I couldn't believe that there is no boot priority options available, which seems the most basic of options...
 
Is there anything that could be done in this situation?

A:how to install windows 10 lenovo g50-70 gpt partition with UEFI

Hi there, Aladil           -
 
Thank you for writing in to the Lenovo Forum - happy to have you here today.
 
You can't install to a GPT drive because you are booting in legacy mode. You'll have to boot in UEFI mode.
 
If you want to install in legacy mode you'll need to convert the drive to MBR - or at least clean it so the installer can partition it MBR-style.  Boot the install media, hit SHIFT+F10 to get a command prompt window, and run DISKPART:  list disk, select disk, clean, exit, exit.  Then let the installation continue.
 
Update us how it goes.

I've tried several discs such as hiren's cd just to try to get to a GUI (mini windows) but always get a bluescreen (trying to load the GUI). I tried GParted, also no luck.

I tried the System recovery from the Novo Button Menu, but all I get is "Default boot device missing or boot failed" it then demands installation media which I already know won't help with recovery.

Hello all. My first post on these forums. Hope I don't break any rules in it
I'll try to be short and clear in describing my problem, but please bare with me here as it's not the simplest of issues (not to me anyway).
I got a (at the time new) MSi laptop several months back with just a regular Windows 8 Core x64 on it and a UEFI boot system (or whatever is the name for "BIOSs"). At some point I had problems with the settings - I couldn't open any of my computer's settings - and I researched long and hard to no avail. So I installed Windows 7 32-bit (the only disk I had). Now, I'm trying to upgrade to Windows 8.1 Pro. I noticed that after the installation of 8.1 Pro my system was still running in 32-bit, so I made a bootable USB stick with the retail version of Windows 8 Core with no key just to get the system back to x64. It worked just fine. I cannot, however, boot in UEFI mode. I believe the partition got wiped somewhere in the Windows 7 installation. Whenever I enter UEFI by pressing the DEL button (I cannot see the UEFI firmware settings tile under the Troubleshoot option) I see the boot mode is LEGACY and when I change it to UEFI, save and reset, it doesn't boot, giving me a "No media found" error. I don't care about my settings/files as long as I get UEFI back with Windows 8.1 Pro running.
I googled long enough to know I'm not going anywhere if I don't ask someone with expertise on this matter.
My next attempt would be to try and install 8.1 Pro fro... Read more

*Already have a decent 8.1 Legacy Windows install in place, but wanted to add a pure UEFI 8.1 installation from my developer 8.1 upgrade iso but found myself without a USB drive of sufficient size to hold all of the Win8.1 installation files.

*But I did have an extra 320GB SATA II hard drive lying around and I thought I'd try and do my UEFI OS installation from a spare internal SATAII drive instead of the recommended USB drive device.(The size here is arbitrary in that it was all I had...;)A ~150GB drive would work fine, too--you just need enough room for the UEFI install partition and the UEFI Windows installation itself, plus any utilities and things you might like to include in your boot partition.)

*First thing I did was wipe the 320GB drive completely, of course, convert it to a GPT drive (from MBR), create a ~4GB partition, format it to FAT32, make it primary and mark it active, assign it a drive letter (H:\) and then copy over all the Win8.1 installation files from my developer iso.

If you didn't guess, the OS here is Windows 8. The internet is full of threads on this topic, but every single one is answered in one or more of the following ways: The first type of answer is something the OP has obviously tried already like "Press F11 to get to the recovery partition". The people writing this don't realise that a clean install of Windows on C: also erases the old UEFI and replaces it with a useless one that isn't linked to the recovery partition.

The next type of answer is "why?". There are at least two painfully obvious reasons why someone would want to restore their laptop to factory condition, but asking which one is entirely off-topic. Until admins ban the question we're all going to have to learn to ignore it.

The rarer type of answer is the one that you can have some respect for. Probably something about active partitions, boot flags or even diskpart if the person knew how to fix this in Windows 7. Bravo to those people.

Some people don't even read the OP, but reply anyway, which is why I've put some things in bold and left the words "recovery partition" to the end of the title. Hopefully they won't see it.
But with Windows 8 and EFI none of that old stuff works anymore. In fact nothing that I'm familiar with seems to work at all anymore, it's all new. It's like being 20 again and not really knowing what's gonna happen when you hit enter.

Good day,

I have an Asus Z68 mainboard with UEFI-BIOS. Windows 7 Professional 64bit is installed in UEFI mode on a GPT partitioned drive (SSD). It worked flawlessly.

Now I added my second, old harddrive, that is still MBR formatted.
Windows won't start anymore, instead I am seeing "Windows is loading files", then a blinking cursor, and that's all.

I have two options in BIOS regarding boot priority:
1) I can boot from the SSD as primary priority
2) I can select an option called "Windows Boot loader", I think this refers to the UEFI boot code that Windows wrote to the UEFI.

If I select the first option, I get the "Windows is loading files screen" and then the "Windows has detected a startup error, do you want to repair the system startup" screen. If I select "Start Windows normally", I get a blinking cursor and then nothing. If I select "Repair startup", I see "Windows is loading files", and then again the "Startup repair screen". It is an endless loop.

If I select the second option, I get "Windows is loading files", then a blinking cursor, and nothing more.

Is there any way to get my Windows to boot again without disconnecting or re-partitioning the old harddrive?

Note that the old harddrive is NOT for booting, as it is just a datastore.

I went to BIOS, and found that my preferences wasn't saved.I'm now in a trap, can't install a OS, can't boot even a CD!What else i can do? Thanks in advance, sorry for bad english

Before Win7 I had Win XP SP3.
I did clean installation (deleted Program Files partition and C:\) partition, but somehow, my "Programming" partition got deleted as well.
It was 10 GB, and had some VERY important data on it.
When I go to Storage Manager, it's shown as part of C: partition, as you can see on image.

Now, when I try to right click it, this is how menu looks:

And, when I try to change it's drive letters and paths, it pops this error:


I have Windows 7 Ultimate x64, build 7100 (RC).

Anyone knows how can I solve this problem?

Few notes:
1. I have 2 Hard Drives - 600 and 240 GB.
2. Unallocated space is for my new XP installation.
3. Partition E:\ is for movies, G:\ is for installations and .exe files, D:\ is "Program Files" partition.

A:Partition problem - Partition deleted or something?

Hi Blazeme welcome to the forums,

Have you tried setting the partition as active? You will need to set 'Mark partition as active' in order to allocate it a drive letter.

I put 7100 on a second partition on my p.c. so I could test it out since I have had to revert to 7000 paritition on this machine on all builds after 7022 due to internet loss bug. However I have solved the problem and am now ready to move the second partition over onto the first one, which I have done before with Win7 since it has a hidden partition with its boot manager and so it doesn't rely on C: drive to boot.

Normally I would use Disk Management to delete the first partiition, then use Partition Magic Pro 9 to move the second partition over onto the first one's free space. It has worked several times so far, but the problem is that I am not sure I want to have as a long-term main partition one which is labeled "F." Is this going to be a problem somewhere down the line? I cannot find a way to change the drive letter on a primary system partition like this to letter "C" which is now available. Any suggestions or do I just need to clean install?

A:Moving 2nd partition onto deleted 1st partition?

No problems will occur. You can change the drive letters by accessing Disk Management, right clicking on the "F" partition, and pressing "Change Drive Letter and Paths". If there is no "C" drive present or "C" has not already been assigned, then it should work.

Hello, I've been wanted to reformat my computer for a while now. So today I deleted my OS's partition, but then I came up with an error saying "windows cannot be installed to this disk GPT." I backed up everything on another partition. But now I can't even access it because I have no OS. I can delete the hard drive clean and install a new windows through there, but that would mean losing all of my data. Is there any way I can boot my computer to recover those files? This is on an ASUS n56, laptop.

Thank you for reading!

A:Deleted my OS partition, but have info on another partition..

What is the exact error message? " windows cannot be installed to this disk GPT." doesn't quite describe the exact problem you are having. Kindly post the full error message, we need the specifics.

What version of Windows do you intend to install? Seven | 8 | 8.1 (32-bit | 64-bit).

How did you delete the OS partition (Windows media or other utility?).

Did you perform any other partition operations other than just deleting the partition? For example, converting from GPT to MBR disk or vice versa, creating new partitions, etc?

I am working on a new Toshiba C55-C laptop, running Windows 10. This laptop also uses a pure UEFI system. I am having trouble getting my Partition Wizard Bootable CDs and USB sticks to start on this machine (all media works with other PCs).

I should also mention that I can get my Easus Partition Master CD (non-UEFI) and Acronis True Image 2014 CDs to boot and start on this machine, as well as Ubuntu 14 on USB stick.
The problem only lies with the PW disks and sticks.

Using PW 9.1 on CD and booting from optical drive in standard UEFI settings I get:
CD Boots
Minitool Partition Wizard option line > I press Enter
then: "error: /boot/bzImage3 has invalid signature" and "error: you need to load the kernal first"
Realizing this has to do with SecureBoot, I got into settings and turned off Secure Boot and TPM
Now, booting the 9.1 CD gets me:
CD Boots
Minitool Partition Wizard option line > I press Enter
PW Files load and scroll down
I get to the screen: "Please choose a display Resolution (1-2-3-4)", I enter 1 and Enter
Result: "1/bin/sh: Can't access TTY; Job control turned off"
Try and other number: "/bin/sh: #: not found"
No further progress
If I try and boot from a bootable USB stick with PW 9.1 I get the same result.
I can boot my older version PW CDs (v7.5, v5.2) if I go into settings and set Advanced > Boot > from UEFI Boot to CSM Boot.
In CSM mode the GPT hard drive is not recognized as a boot device, so th... Read more

Hallo,

After creating a UEFI bootable USB thumb drive with Rufus (using Windows 8.1 Enterprise ISO x64), for a Dell Optiplex 3010 (configured as UEFI only, no CSM, latest firmware version, Windows 8 installed), I didn't see a USB boot option, so I tried to add one manually. Unfortunately I erased the existing boot option (boot manager) by mistake. Although there were two boot options for PXE booting, the machine will not start anymore, even when there is an active WDS server on the network.

I also see Led's 2 and 3 lighting up, meaning according to the manual 'hardware ok but bios possibly damaged/corrupt'.

I understand I cannot start the machine from a bios boot disk because of GPT partitioning, and the UEFI USB boot disk I made might be corrupt (as it didn't show up as a boot option), however I don't understand why it won't boot from the PXE network card, as these boot options are still there.

Any suggestions on how to solve this?

Thanks for any useful tips,
Bavo

A:Deleted Uefi boot option (Windows Boot Manager) by mistake

The Windows Boot Manager is held in the Bios and restores itself if you boot to a UEFI capable device. Could you please explain exactly what you did to "Add" the USB boot option?

I haven't used Rufus since it is so easy to just format the drive yourself, but it did format in Fat32?

I have the PXE boot options disabled in my bios since I do not have a network boot option.

I'm not sure if this goes here, but I deleted a partition on a slave hard drive and then I created a new partition over it. But I haven't formatted it. Now I just found out that there was data on that partition that I really need but I don't know how to get it back if I have a partition over it now that isn't formatted. Help!

Try using data recovery software. You will likely need to use "scan" mode, which will read all of the sectors of the HDD (and will take awhile). I've had decent luck with EaseUS.

Hello tazloccsta and welcome to Seven Forums.

I'm guessing you used HP Disk Sanitizer. As you probably know, this is a utility that can securely erase all data from a hard drive.

HP ProtectTools - keep data, networks and communications protected from threats

Ordinarily I'd suggest you try to return your computer to a previous condition by using a restore point from a date/time prior to using Disk Sanitizer. But I'm not at all confident this would work. It would be way too easy for an unauthorized person to gain access to your computer and "undelete" the data you thought had been securely deleted. But you can give it a try.

System Restore

One of the Forum experts has prepared a couple of troubleshooting guides that may help.

Troubleshooting Windows 7 Failure to Boot

Troubleshooting Steps for Windows 7

Or you might want to skip directly to a repair install. It will try to fix your currently installed Windows 7 and preserve your user accounts, data, programs, system drivers, etc. It would probably take less than an hour and if it works, you'd just have to reinstall Windows Updates.

Repair Install

You could also use this opportunity to do a clean reinstall and eliminate the HP bloatware and useless factory installed utilities that just slow down a machine.

Thanks so much!

Hey guys,

So this is my problem:

I have a 500GB Maxtor Hard disk, and I went to install windows xp, but during the installation i saw that it was split into different partitions. I have no idea why but i deleted one of them. Now i think the entire hard disk is screwed up. When i connected it to my laptop using a SATA docking station, under disk management it gives me my C drive which is disk 0 and it gives me the Maxtor hard disk which is disk 1. But disk 1 is split into 100mb, 60Gb and 405.66 GB with the 405.66 being unallocated. What should i do to make it 1 500GB harddisk.

Pls Helpp!!!
 

A:Please help with deleted partition

Assuming the disk does not contain an operating system, or any personal data you need, just remove the partitions, so the whole disk is unallocated, then create a simple partition the entire size of the disk e.g. 465GB in size.

I own a Dell Studio 1555 laptop having Vista 32-bit. But it was giving problems so i wanted to install Windows XP, so when I inserted the disc, after loading all the drivers it showed a blue screen. I tried several times but same error was coming. I was having a DOS disc, with that i deleted the partitions coz i was thinking the recovery drive was not allowing me to install XP. But now neither i can create a partition nor i can install any OS. Please suggest what to do ?

Moreover is there any chance of warranty being void since i bought it just 4 months back ?

Hello Ayan007, welcome to Seven Forums!



If you didn't create the "Recovery Disks" before you deleted the "Recovery Partition" then you may have done away with the only way to recover your PC if ever you have any issues that require you to do a "Factory Recovery"; if it was the "D: Recovery" partition it's probably not big enough to install an OS on, how big is it?
