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.)

I bought a new Samsung SSD with self-encrypting capabilities.In the HP Bios/settings, I had the possibility to put a "drive lock" on the disk (I think it's OPAL). I installed an OS, worked for a couple of weeks, everything went fine. During startup, I always had to enter a password to unlock the drive, which is exactly what I wanted. Today, I booted the notebook again, this time I maybe mistyped the password two times, now the drive is locked. I do have the correct password here, but I can't find an option within the BIOS to unlock the drive. No matter where I click within the BIOS, it always tell's me "Drive is Locked". Now, how can I *unlock* the drive when I have the correct password?I tried:  * Security -> DriveLock -> "Set DriveLock Password" -> Error: Drive is Locked  * Security -> DriveLock -> disable "DriveLock password on restart" -> has no effect Help

Just want to start off with saying I have read another similar post on this site which can be found here: [SOLVED] Startup Repair cannot repair this computer automatically.

It was promising as the poster was having the exact same errors as me fro the people recommending fixes as me but in the end it turned out he jut had a faulty piece of software. This is what I have done so fa an had no luck with.

I was running windows 10 but im currently running it from a USB stick.

So I was able to stick a memory stick in my PC hoping to reinstall windows on my second hard dive, but I noticed that my first hard drive wasn't dead after all as it wasn't letting me re format hard drive #2 for what ever reasons so I started browsing the tools.

I have gone through countless forums and tried all of this:

A lot of the forums recommended doing these commands, I got to the last one and it always said this:

After the power strip was turned off by my 5 year old granddaughter my computer won't boot. It tries to repair itself but fails. I have tried tapping F12 to get to the boot menu but everything I have tried has failed. I don't have a recovery disk. Lesson learned there. I had the computer diagnose the startup and it found no problems.

I have tried to reset it but I get a message that says, "A required drive partition is missing."

If I try to refresh it says, "The drive where Windows is installed is locked. Unlock the drive and try again."

It has a Seagate hard drive #ST500DM002.

Can anybody tell me how to unlock the drive or anything else that would help? My computer skills are very limited.

Used Lenovo OS recovery DVD's for Win8.1 to setup machine (old system crashed and couldn't be recovered) back to factory default. Once in Windows, used the Recovery tool (Control Panel -> Recovery) to create a recovery USB drive. Followed instructions from https://support.lenovo.com/us/en/solutions/ht080887 and created a recovery USB drive. I then wanted to test this drive before I loaded all my applications and again followed the instructions in that article to "reset pc" using the USB drive. It appeared to reset the pc (I watched it go from 0% up to just about 100%) and then it rebooted. After reboot, it went right back into the USB recovery drive. I removed the USB drive and rebooted it again, and got a "no operating system..." error. When I insert the USB recovery drive back in and use the utility, it tells me the drive is locked. This tells me it didn't "reset pc" like it was supposed to do, but I followed everything to a "t". Any suggestions?

Windows 7 Home Premium 64-bit
Western Digital WD My Passport 2 TB external hard drive
Western Digital's security software allows a password to be set on the external drive, encrypting it. When the drive is connected to a PC, a virtual CD (VCD) partition runs (via autorun) an unlocker utility WD Drive Unlock.exe, that allows password entry.
When I connect the locked drive to a Windows 7 PC (that does not have any WD software installed), the autoun popup appears and I select "Run WD Drive Unlock.exe". At that point, User Account Control (UAC) elevation prompt appears, requiring Administrator
password in order to continue.
WD Drive Unlock then lets me enter password.
Because of UAC elevation, the unlocker can be used only by an Administrator user or by a standard user account who knows the Administrator password.

Is UAC elevation prompt truly necessary?
Is it appearing because Western Digital hasn't coded the unlocker exe correctly, or would any such utility require UAC elevation?

I'd like to find a way that a standard user account can run the unlocker to enter passsword and access the external drive, without having to know the Windows Admin password.

A:How do I unlock C: Drive on Windows XP ?


The HDD is locked when its in use usually. The LOCK command blocks direct access by programs that can corrupt file names and/or destroy disk data, resulting in the loss of files on your disk. I've never used this piece of software but you won't have to use the HDD repair function, Windows has one that is perfectly adequate and suited for it.

-Go to Start>Run>type: chkdsk /r and hit enter.
-You will be prompted and choose Y and reboot.
-It will run on restart and do all the necessary checks/repairs needed tp your HDD.

On a side note, in Command Prompt this is how to lock unlock a drive.

LOCK [drive:]

Hit enter and choose Y. Its locked now. For instance drive C: would be:


For unlocking

UNLOCK [drive:]

The same as before, you would type unlock followed by drive location.

Let us know how that goes.

I have a dual boot system with WinXP and Win7 on the same drive, partitioned out. I also have a second drive which contains most of my data files.

For some reason, Win7 isn't seeing my XP partition, however it has no problems seeing my data drive. XP can also successfully see the new Win7 partition when I boot into XP.

Is there a reason why Win7 can't see my XP partition? Is there a way to fix this? Doing a search on this was quite hard. I kept getting all sorts of irrelevant results (most about full missing hds which isn't my problem).

Hi again guice,

Win 7 does that on purpose. If you wish to see your XP partition while in 7, do this :

Boot into 7, go into Disk Management, right click the XP partition, and assign a drive letter - best accept the one it offers by default.

I had to recover my laptop to factory settings due to blue screen errors and not being able to launch windows. It kept restarting itself and blue screen errors and restarting itself "endless cycle"

I have 5 DVD recovery or restore to factory settings discs. The first time I put in the first recovery DVD upon reboot and I tried this option in system recovery manager f 11, "System recovery Wipe Drives and Reset to factory settings" but it did not complete successfully after restoration process finished and after "software is being installed" appeared on the screen.

It showed a window that gave only three options: "Save Log, Details and Retry"
When I clicked on retry, a window popped up saying "Insert Recovery Media"

I re-inserted the first recovery DVDs out of the 5 and the message window "Insert recovery media" did not close. I was stuck and could not go any further.

I forcefully shut down the computer; restarted and I chose the second option which was "System restore to factory settings" After inserting disc 1 through 5 in chronological order, It went through the whole process and completed.

Now, in disk defragmenter, disk cleanup, disk management and my pc a.k.a. "My computer"...it shows C drive and my BD-rom drive as D. The BD-ROM is suppose to be E, but it is listed as D.

Hi There

I upgraded a HP laptop to the newest windows 10 version and as per organization requirements started bitlocker encryption on the windows drive.  While the encryption was running the user who uses the computer, for some reason had restarted
the computer while encryption was in progress.

After the restart, it showed an error 0xc0000225 "Unable to find file winload.exe" 
It was not displaying the Bitlocker unlock screen so as to unlock the drive.
I also saved the recovery key and have it printed. 
Although after booting using a win10 usb and using CMD off the bootable usb to try unlock the drive, it did not work.
I used the command  x:\>windows\system32> manage-bde -unlock e: -rp "the 48digit key" 
but it said the password wasnt able to unlock the drive. Not sure why as I have the right key. 
Also note that I used the new encryption method that works only on windows 10.

I also tried removing the harddisk and connecting it to another PC that has windows 10 version 1511 and when clicking unlock drive it says that I need a newer version of windows to unlock the drive. How can that be when I have the newest version??

The user has some important data to recover and any help is appreciated to unlock the drive

Have you looked at the size of the drive? when you right click and select properties, does the pie chart say the drive is full or empty?

Is there a way for me to recover the erased factory partitions? Nothing has been done to the drive since erasing it.

all day today I have been attempting to repair my laptop from an unknown failure. I have recovery tools and a fresh copy of Windows 10 on an 8 gigabyte flash drive and tried to reinstall Windows 10 to finally use my laptop again. everytime I go into the recovery Tools in attempt to reset or refresh my computer it says a required drive partition is missing. please help.

A:Required Drive Partition Missing

The cause for this error is normally a corrupt MBR or BCD file. To resolve this issue, there are a few things you may want to try.
Boot into Advanced Boot Options. From the WinRE screen, select Troubleshoot > Advanced options > Command Prompt. Run Check Disk using CMD. You may use the chkdsk /r command.
If a system file required for booting up has become corrupted, running System File Checker may help you.
You may be required to change the active partition using diskpart. An Active partition is the one that your BIOS detects is the one that will start your computer.
It is important to note that changing Active Partition wrongly may make your computer unbootable. So do not by mistake, mark a partition as Active, if it does not contain the NTDLR loader for your operating system.

Formatted the computer and probably forgot about creating a new partition for the second one. I have two hard drives (not external). How do I reinstall the second hard drive without formatting the whole computer?

A:Missing hard drive, partition?

Formatting requires you to choose a partition, and it will only format that partition. No other partition is affected. So you cannot accidentally format another drive or partition when you format the C drive -- it's just not possible.

If you've got Windows up & running & you want to create a partition on the second drive, go to Control Panel --> Administrative Tools --> Computer Management.

Then click "Disk Management" in the right-hand tree.

A friend of mine gave me his external hard drive with the hopes that I might be able to fix it.

It's a new external Western Digital that is 2TB in size and he purchased it within the last 2 or 3 months. I don't know what he did, but it wouldn't surprise me if he pulled the USB cord without properly unmounting the drive and something with his filesystem became corrupted. I don't know how to repair this.

The drive will show you a drive letter when you attach it to Windows, and using a partition manager (in Linux) shows the drive to contain an "unknown" partition type. In Windows, running "chkdsk e: /x /r" returns an error that says "chkdsk is not available for RAW drives".

Anyone know of a reliable (and preferably free) utility that might be able to repair this kind of problem quickly?

A:External hard drive NTFS partition missing; chkdsk says it's a "RAW" partition now

Is this a data recovery operation? Should be able to just format again if not.

Otherwise testdisk (http://www.cgsecurity.org/wiki/TestDisk) might be useful to recover the partition info.

I completed this and when i went onto my computer it showed up as 300 gigs total space. So i enter disk management and reformat it and extended the space to 2100 gigs the highest option. I thought that i could get more some how and i somehow ended up deleting the partition. Since then i was not able to see the drive in My computer or disk management so i installed a software (EaseUS Data Recovery) and am now currently doing a scan of the the drive to recover it.

A:unable to reset pc.a required drive partition is missing.

You have to destroy(delete) all partitions on disk 0 then reformat to NTFS. A good tool is GParted, or if you're experienced with CLI use command prompt in WinPe. Gparted is easier being visual. just go here to find the latest ISO, pick live usb or dvd and burn it. Then boot into it, and then pick all partitions to delete and reformat entire disk to NTFS. When complete shutdown, swap out GParted for recovery media(USB or better system image) and then reboot. p.s a copy of GParted also comes with ubuntu based OS?s.

I have read many posts about this here but many of them talk about WinXP. I also have read some solutions but want to have some verification before I proceed. Here is what happened:
I have 3 hard drives connected to the computer. They are of varying sizes and brands. Hard drive #1 is a 30gb Maxtor (this originally had the OS on it but I deleted all and installed Win2000 on hard drive #2....this was a long time ago). Hard drive #2 is a WD 10gb. Hard drive #3 is a WD120 GB. I had Hard drive #1 set up as the master due to the OS being on this a long time ago. When I installed the OS on hard drive #2, I forgot to change it to the master, so it was still set as a slave and number 3 in the boot order. So after that, this was the standing order:
first to boot--- hard drive #1(misc data only)
second---- cdrw
third---- hard drive #2 (with OS on it)
Fourth---- hard drive #3 (misc data only)

This worked fine with no problems at all until I decided to delete all partitions on hard drive #1. This hard drive had not been used for a long time anyway and the data on it had been cloned to the hard drive #3 (into 2 partitions). It should be noted that I was using Roxio's Goback personal edition until now. Before deleting the partitions on hard drive #3, I had to disable GoBack. I did that and used Partitionmagic 8.0 to delete the 2 partitions on hard drive #3. When I clicked "Apply", it reminded me that this partition was set as active and if I deleted it than I would have to s... Read more

I have been searching for days around the net for a way to resolve this and haven't seen anything that can help me thus far, so hopefully one of you kind people may be able to help.....

I had a bit of a hard drive issue a few days ago.... my D: Drive disappeared... it's a partition on my Hard drive which I just use for music/photos etc.... it was there on Monday..... I did a full (Windows) back up (thank God) on Monday evening as I was planning on installing some software a few days later.....

I have an Acer 8920G running Windows 7.

Then on Tuesday my Acer proprietary media player needed lots of updates performed to it (it was the first time I had actually needed to play a Blu Ray disc in my laptop for over a year so I guess all the updates were successive).

When I rebooted for the final time, I noticed my D: drive was gone. Now, the thing is, I cannot be sure that the updates to the Acer Media Player was the issue but that is the only change that was made to the laptop since the back up.

I tried restoring my system back to a time point from Monday (when I knew the D: Drive was present)... still didn't come back. I then looked on Disk Management.... the only partition that is showing up with a letter is the C: drive.... there are three other partitions... the recovery one, another small one (not sure what that is) and then the 140GB one that says "Healthy. OME partition" or something like that.... I cannot assign a letter to it by right clicking on it ... Read more

A:Internal Hard Drive Logical Partition now missing...


What has happened to the space the old partition occupied? Is it unallocated space?

Could you please post a screenshot of your disk management window, and describe where the partition was?

A:help "unable to reset your pc. a required drive partition is missing"

My sister-in-law took her PC into the Geek Squad (she lives in another state), and they screwed it up.  They f'd around and removed an excellant Antivirus program, and firewall and replaced the antivirus with a POS program.  Even the manufacturer of the substandard antivirus programs says it is only intended as a baseline, and recommends programs like AVAST, NORTON, etc.  The Geek Squad are, well to be nice, incompentant b**bs .  This isn't the first time I had to help my sister-in-law, remotely, to fix the Geek Squad's debacle.
So I suspect that the "recovery disk" they created was just another screwup.  When I went from Windows 8 (manufacturer's image), to 8.1 (boxed from M$), I had to delete all partitions, and then when I booted from the DVD, partitioned out my drive the way I wanted, then the OS installed.
I don't know if that will help you much, but I thought I'd put in my 2 cents.

Wanted to do the whole "Remove everything & re-install Windows" thing, but funnily enough I can't and the reason why baffles me so . . .

From the desktop I select the option, It'll just restart my computer and ask me my language and than provides me the the following reset PC option, I click thee icon does the whole circle loading and gives me the nice single sentence, Unable to reset your PC - A Required HD Drive partition Is missing.

So I swiftly restart the computer and It gives me the Windows boot manager screen, Windows Setup or Win8
Win8 obviously works but WS just splats the error oxc000000F

I'd rather not book the Desktop Into the techies as-a few years back I broke "G" key on my laptop, I simply wanted It replaced & funnily enough It cost ?90 which I just had to laugh or cry <3
If my post Is missing any vitals than ask 4 them, doing nothing today as I'm finishing Sonic All-stars so I can trade It In : /

A:Unable to reset PC - Required Hardrive Drive partition Is missing?

Did you create a "Recovery DVD" or system image when you first setup Windows 8? If so, you can backup whatever personal files you've added since then, and then run your recovery procedure. If your PC came with an OEM recovery partition (sometimes different than the MS Windows partition), a key-combination at startup can sometimes effect a clean re-install in that manner. The details would be in the user manual for your system. And, of course, if you have a Windows 8 installation DVD, you can simply boot from that and run a full re-install - it will re-create partitions as necessary.

If the above doesn't apply:
Did you make any changes to the partitioning on your hard drive(s)?
Did you add a hard drive?
Did you run any diagnostics on your hard drive(s)?

Yet another possibility, if you happen to have a "Windows 8 repair disk" (different from a recovery or system-image disk) --- you could try starting the PC with that & trying the "System Reset" option from there. This would only work if the trouble is some sort of bug in the System Reset program files currently on the hard drive. You can use a "repair disk" created from a different computer, so long as it is for the same version and bit-depth of Windows 8 that you have. You continue to use the license and product key or your original Windows 8.

Best of luck

two weeks ago i was bought a Fujitsu B series lifebook computer.About 5 days ago I had got that virus stating I had a "processor running at 83 degrees", "hard drive clusters are partly damaged", "must scan to fix this issue", yatta yatta yatta and some other classic virus jive talk i cant remember at this moment. At first it kept bothering me about the scan, then it started popping up 57 windows in short succesion, then i couldnt access my other files, then my desk top went black and was reduced to 4 icons, start menu was obliterated.try combo fix, trend micro, some other reliable programs but i would either down load them and they'd disappear or in the case of combofix it would load then exit out quickly. It reached a point were i just couldn't boot my computer up anymore.NTLDR was missing it said. I am not sure if that virus deleted it or if the computer and its hd were just old and wore out. It was from the flea market.. I cant get past that error msg, there is no flash drive boot up option on this old thing, i have no floppy drive with it, it has no cd rom drive, ive heard the external usb cd rom drive cant be used to boot it up but im not 100 percent sure.Someone else with the same notebook reported that it would not allow usb cd rom drive boot up. I have been told network boot is an option but i was told thats just to access it after its turned on and its not what i think its for. I was told an hd switch was a good option but i dont...

I want to prepare a factory fresh drive so that I can use it to save backup images. Soon I will have a second drive that will only be used to store data files. Neither drive will ever be used for the installation of an operating system. From what I've read, I see no advantage to having more than a single partition on either drive. I know I want to use NTFS.

This should be straightforward. I'm finding it is not. I cannot formulate a search that points me to the right tutorial or thread. Either I get hundreds of options to consider or, if I try to narrow the options, no answer is found.

Please point me to the right discussion. Perhaps the answer will help others who come after me, too.



A:Format & Partition New Drive to Use as a Backup Drive or Storage Drive

Do you know how to make a partition and format a drive?

You can do it all in Windows Disk Management.

You don't need to do anything special to the drive just because it is going to store images.
Treat it like any other drive.

Format it with a single partition.

Store your image files on it. Use a folder structure if you want to---perhaps naming a folder something like "Macrium image of C partition, 060714" so you know the date of the image.

Nor do you need to use a separate drive just for image storage.

Make your images and store them like ordinary data. Back up the images just like you'd back up any other important data file. That's what they are: important data.

I had a simple question about Windows 7 Enterprise. I am a computer technician in a corporation serviceing 7000+ PC's. In the past (on Windows XP Professional) when a user would lock the computer we as administrators could unlock the computer and
force the log off of the user. Can this feature or one similar be applied In Windows 7 Enterprise if Fast User switching is turned off?
