Windows 8 Won't Load - Unable To Reset / Required Drive Partition Is Missing
Apr 8, 2014
My Toshiba Satellite Laptop has Windows 8. For some reason windows 8 wont load. It gets to the screen where you select which username you want. But from there its non responsive, I cant get into Windows, I cant restart to load it up in safe mode.
I got a Windows 8 disk which I had to change the bios to load it up. The cd loads but it says the automatic repair wont repair the laptop. I try to refresh windows 8 but I get a message saying the drive where windows is installed is locked. unlock the drive and try again. It also wont let me use system restore.
I try to use the reset pc option but I get a message saying unable to reset your pc, a required drive partition is missing.
At the start it gives me the option to install windows 8, I don't know whether to just do that? Is it ok to do with windows 8 already installed?

I was using Ubuntu 14.04 on my laptop before. Now I want to install Windows 8. I have laptop's rescue CD. I get the following error when I tried to install Windows 8 on UEFI using the rescue CD:
"Unable to reset your pc a required partition is missing".
I think I have a problem about partitions type because Ubuntu uses ext4.

I recently purchased an Asus X551 laptop with Windows 8 but straight the way uninstalled Windows 8 and installed Ubuntu (after creating a Windows 8 recovery drive just in case). I have since decided that I want Windows 8 back as I have found that I cannot use a lot of software on Linux. The laptop did not come with any form of recovery disk or installation disk, the only reminent of Windows 8 I have is the recovery USB that I created from within the OS.
When I plug in the USB and boot from it it brings up the recovery menu with options to reset the PC but when I click it it says something like - "Unable to reset PC. A required partition is missing".

I have an ASUS VivoBook X200CA that is running a Windows 8.1 Upgrade. For about 5 months, this laptop has been running perfectly without any problems and I have managed to reset the computer many times due to certain errors and problems that have arisen from software and hardware compatibility.
Recently, I went to reset my laptop, it restarted and then it took me to the WinRE screen. I went into Troubleshooting > Advanced Options and I clicked on the Reset option. It then took me through each of the various warnings and making sure that my data was backed up and then, once I had clicked on the "Reset" button, it hung for a bit and then said "Reset has failed - Required Partition is Missing".

I have an i7 ASUS Ultrabook (HDD is 2xssd in raid0, UEFI, GPT partitions.) which is great but have an issue where wifi profiles don't retain and i'm not too concerned about retaining the data on the ultrabook so after attempting to fix the wifi profiles not saving (Have been through the driver scenario, folder permissions, sfc, etc and no joy) i'm just going to do a clean install from the recovery partition.
I started by trying the recovery methods 8 has built in, refresh the files, but fails without an error and makes no changes. Attempted to do a full restore via 8 recovery also but fails with no error also and then I realized I was actually missing the OEM options (F9 during boot doesn't allow for EMS boot to begin recovery from recovery partition like expected, just boots into normal recovery).
After installing windows 8.1 it no longer allows me to do an OEM recovery via Windows 8.1's built in recovery methods so I created a recovery USB from the recovery partition using the windows 8 tool since the AI Recovery Burner doesn't recognize the partition, the USB recovery creation did recognize the partition and allow me to create the USB recovery drive from this successfully.
When running the USB recovery, the recovery fails with "Required drive partition is missing"
I think this is because the recovery partition is actually a windows 8 partition, not 8.1, and will not work.
Seems like a lot of effort but I want to retain the OEM key and software set (because it's surprisingly not a piece of trash) so was thinking if I install windows 8 (I have an ISO and another key) over the existing 8.1 partition it may actually allow me to then do the normal recovery.
Since the recovery drive did not work I decided to clone the recovery partition and have the WIM file now, although since cloning the partition when running recovery I no longer have the option to create a recovery drive using the recovery partition, the partitions no longer show as recovery partitions in disk management but instead as OEM partitions (Not sure why this changed.)
The recovery xml configuration for REAGENTC does have the correct GUID's and offsets for the partitions although when running this in elevated cmd it results in error 3 unable to run.
Am I able to create a base recovery drive from another windows 8.1 pc and use the WIM file?
Any way to tell what partition table my created recovery drive is expecting so I can adjust the current partitions to match and perform the recovery? When I try to refresh the files from this recovery I get the error "Windows system is locked" which is why I went for the full recovery.

I built my own PC last year and I've done several OS upgrades in that time frame. First I started with windows 7 basic which I then promptly upgraded to 7 ultimate because my university offered upgrades for $7. I then upgraded to 8 when it first came out and then 8.1 too. I put a new SSD in my PC and copied all my 8.1 data on to it I then turned the old SSD in to a second boot drive for OS X. I'm having problems with 8.1. I wanted to create a repair drive to hopefully root out and fix whatever is causing windows explorer to crash. It's not a virus I've made sure of that. I have a feeling whatever caused this happened when I upgraded to 8.1 and then copied over the SSD. What my product key is for 8.1 pro i just found the email microsoft sent me with my windows 8 key but i have no disc.
when i followed the instructions to make a recovery drive it told me that some of the required files are missing and to use a windows installation disc or media which is a problem because all my windows 8 upgrades have been done online.
also my PC currently doesn't have a disc drive i removed it because i only ever used it to install windows 7 basic.

I am trying to install the new develp build of Windows 8 (x86) on my asus eeepc 1005pe. This is a netbook which doesnt even have a cd/dvd drive.
So anyway, I extracted the iso on a bootable usb flash drive. I boot, and when I click install it just hangs for about 10 minutes and then it gives me this error:
I tried setting the bios from AHCI to IDE. This does not work, I even get a bluescreen of death when I boot up in the current win7 sp1 install. But anyway on google I read a lot about this problem and one of the solutions is to put it on AHCI.. but not for me as it was already on AHCI. Anyway IDE is not workin either.
Just recently I installed win7sp1 on this netbook without a problem. I checked the sha1 hashes of the Windows 8 ISO and they are confirmed, so that is not the problem either.

I bought an Asus Vivobook S551LB. Paying around 1150 for it, the specs seemed good and I thought it'd be a fairly quick laptop.
Turns out... It's really slow, and freezes a lot.
It was preinstalled with Windows 8, then I updated to 8.1. I'm fairly new to anything past Windows 7 so, 8 I'm completely lost.
I deleted all the bloatware that came with the laptop but it still freezes, so my last resort is to reinstall windows.
I can't because I updated to Windows 8.1 and when I try to reset it says I'm missing a partition.

I am trying to run a reset in Windows 8. However, after rebooting into WinRE, it says that it can't reset because I am missing a required partition.
I searched for a solution to this problem. But, it looks like most people who see this error have accidentally deleted some Windows partitions. In my case, I have not altered the Windows partitions since original install.
I read another comment that suggested that it's due to the hd driver being missing and that I would have to "inject" the correct driver into winre. But, I'm not sure how to do that (or if that is really the fix).

I accidentally deleted the EFI partition, required to boot into my Win 8.1 installation - unbeknownst to me that EFI partition was on a different disk to where my Windows is located. To complicate matters the Windows install is on a RAID0 array.
Windows repair using the original install media didn't work.
EasyRE didn't detect the RAID0 drive.I saw various instructions on how to reconstruct the EFI partition, but they all assumed that the EFI partition is still there, which in my case it isn't.how I can get my data off that drive and re-install Windows?

When I start my computer (which is running win 8), yahoo messenger won't sign in, and certain websites won't load for me for about 10-15 minutes. So it's just for certain websites, and the yahoo messenger client. Skype and 90% of the websites load with no problems whatsoever. And it only happens after i turn on my machine, or after a restart.
The problem persists no matter what browsers i use. When i ping those websites, I get replies from them, everything looks just fine, but they just won't load. After 10-15 minutes, they just fire up, all at once and i get no problems whatsoever. It's not a problem with the internet connection, as I got another windows running machine, an iPad, and my gf's Mac, and none of them are experiencing this issue. Plus, it also happens when i'm using any other network from a different location.
I have flushed my dns, and have run antivirus solutions like dr. web, combofix and malwarebyes anti-malware, and still no joy. My windows updates are up to date.. Do you need any other info for a diagnostic?

I want to partition my C Drive to install Ubuntu 14.04 so I can dual-boot with Windows 8.1. When I tried to shrink the volume it wouldn't let me got higher than 4GB even though its a 500GB drive and I have over 259GB free. From looking at it the drive seems to have a few recovery partitions one being just under 24GB. Does the number of drive partitions factor into the amount of space I can give to a partition. Also if the recovery partitions are factoring into this can I move them to another drive or just outright delete them.

I've got a windows 8 laptop which gives me this error message when i try to switch it on:
"Your PC needs to be repaired The boot configuration data file is missing some required information.
File:BCD Error Code : 0xc000000d ............................" I'm sure you are all familiar with the rest of this dreaded error code.
I've tried all the repair options, recovery disks to a windows 8 bootable flash disk, the command prompt fix boot commands as well but still I get the same error message whenever i try to boot windows.
Now I'd like to know, can't i just copy the boot folders from another similar windows 8 pc and paste them into my harddrive to fix this?

I am running two 7950s in crossfire on my computer. Anytime I launch a game, my computer just locks up and this hardcore buzzing sound playing right when it crashes, the sound continues while the computer is frozen.
This problem has happened in both Battlefield 3 and Splinter Cell Blacklist. I have enabled Crossfire and Crossfire for applications that have no associated profile. In GPUz, it says my cards are enabled for crossfire.
I'm wondering if it's my psu? If I disable crossfire, the games work, but the second gpu is at 0% utilization.
Here are my specs:
Windows 8 64bit
AMD 13.8 beta 2 drivers
ULPS is disabled via MSI Afterburner (and I did restart after)
CPU: 4670k
Motherboard: Gigabyte Z87x-UD5H
RAM: 16GB Gskill
HDD: OS on a 120gb ssd, games on a 2tb WD Black
PSU: 750w Corsair

I have recently built my own pc.
Operating system is windows 8.1
motherboard is ASROCK FM2A58M-HD+
500 gb hard drive and 4 gb Ram
For about the last week or so my Norton 360 has been picking up a threat, every time I turn my pc on. I thought Norton was getting rid of It so I didn't pay to much attention until my media player kept playing up and certain programs wouldn't load or take a long time, so I did some research and it turned out to be a trojen. anyway I have tried to put my pc into safe mode and have restarted my pc. my operating system wont load back up.
I have a red screen with a power button that gives me the option to restart or shut down. and there is a ease of access button. I have tried repairing with the original disk but it say my hard drive is locked. and it wont let me reinstall it either.

I have an Asus gaming laptop that I got off of Craigslist awhile back. It did not come with any factory disks. I'm trying to do a factory reset and it says "Some files are missing. Your Windows installation or recovery media will provide these files." But I don't have any recovery media.

I have a Dell Latitude E6500. Before tonight, I was running Windows 7. I decided to update to Windows 8 and now I am unable to get any web pages to load. My wireless is connected but no pages will load when I open IE.
I can't imagine I am the only one who has run in to this.
Maybe it's a device driver; but I can't get to the Dell site to do any diagnostics.

Since receiving my laptop back from it being repaired (Fan wasn't spinning then the laptop wouldn't turn on after trying to fix it myself) it turns on and the fan spins just fine although I am having numerous software problems.
First, I can't open my photos, music or documents folder (videos seems to be fine) and they don't have their original icons anymore, when I try to open the folders using the file explorer nothing happens, when I tried to open folder using the tiles, the folder would load then close without warning or reason and when I tried opening files by right clicking > open with, it would open then a banner will show saying. 'You don't have permission to access this' (Or something similar).
I am able to access my photos and such by going to: Computer > Local Disk (C: ) > Users > [My name], in there I can find it all but it's not where it should be.
After this I decided to restore my pc to an earlier point, but since then my tiles have vanished (Photos, music, Skype, videos, people and so on) although the Store tile seems to have stayed and is working fine.
While trying to reinstall the tiles from the store, the store says I already have the tiles but I can't find them anywhere.
I eventually decided to reset my system and reinstall windows (I would be reverted to Windows 8 not 8.1) although while attempting a reset, a banner shows up saying. 'There was a problem while resetting your PC'. When clicking 'Check for solutions to this problem' it would minimise the window to the desktop and then nothing would happen.
I want my old PC back, before it needed repairing!

I'm having trouble getting windows 8 to detect my RTL8188CU after installing the Windows 7 x64 drivers from realtek on Windows consumer preview. I had the exact same issue in developer preview and I was unable to solve it. I'm not sure wether doing a fresh install would solve issues rather than an upgrade to keep personal files.

I've had a lot of trouble with my samsung laptop. The HDD has been replaced but I now cannot do a refresh or reset. I get the message"Some files are missing. Your Windows installation or recovery media will provide these files". The laptop came with Windows 8 installed so I do not have the installation discs. I can do a factory restore by pressing f4 on start up successfully but still shows the above message trying to refresh. What caused this and what can I do about it?

i'm using Windows 8 Home 64 Bit.
I used AOMEI Partition Assistant Standard to add a NTFS Partition to my USB drive. I want to store large files over 4GB on this partition, while having the rest of my files on the primary partition which is FAT32. The problem is, when I plug my drive into the computer it only shows the primary partition.
Is there any way to get Windows to show both partitions when I plug the device in? I want to be able to store files on both partitions.
After doing some research, I found that one possible way would be to set the USB device as a "Fixed disk". I was unable to figure out how to do this.
The device is a 32GB Silicon Power Blaze Removable Disk with USB 3.0.

I swapped the HDD with a new blank SSD in T530 and booted it with the recovery USB of windows 8. System boots from the USB and gives refresh, reset, and other options. However, when I select reset ( to fresh isntall the OS on the SSD), it fails saying a required partition is missing. What! I'm using a blank SSD, shouldn't the installer present me with options to format and use the drive rather than erring out?
Is there any better way of installing the windows 8 os on a new blank SSD using the recovery USB?
I do have gParted live USB. If nothing works, I will partition the SSD using gParted and try the Windows 8 recovery USB again.

I've got a new desktop which is connected to my house wifi using an USB adaptor. The signal quality is constantly at 5 bars but I find myself frequently having to refresh multiple times whenever I load a new page on the browser either because it's not loading or pictures or not showing. Pages become near impossible to load when i am downloading stuff(torrents, upgrades, games etc). Also noticed other computers in the house are also affecting mine when they are in the process of downloading files. Torrents, updates all make it impossible for me to browse the net. Pages literally refuse to be loaded at all whenever something is downloading. I also have to infrequently refresh pages even when nothing is downloading because it's not loading or pictures are not showing. None of the other computers are affected however.
Any program that requires an internet access is also struggling to get connected. I had to use direct links to install certain programs such as Adobe reader/flash. It's often impossible to check for updates in programs or even sign on to clients like Steam/Origin which requires a connection. I had to try for ages before it signed in online but it's still having trouble loading images and such.
What is strange however is that I'm having no issues holding a connection when downloading bigger files such as direct downloads, windows update, steam game downloads and torrents. No drop outs that I've noticed. But it is faily slow averaging 400kb/s.
Everything else in my house including my laptop, another desktop, ipad and phone works fine. No issue browsing the net while downloading.
Wireless is connected through an USB adaptor pluged in to the back of my desktop. I've tried two adaptors (ASUS USB-N13 and Linksys AE1200) and both of them runs into the same problems. Running windows 8.1 and using ESET NOD32 as an antivirus with the windows firewall turned on. Desktop specs are as follows:
CPU: i5 4670K
Mobo: Gigabyte GA-Z87X-UD3H
RAM: G.Skill Ares F3-1866C9D-8GAB 8GB (2x4GB)
GPU: EVGA GeForce GTX 780
SSD: Samsung 840 EVO Series 250GB
HDD: Seagate 2TB
OS: Windows 8.1
This is extremely frustrating and has never happened with any other computers I've used before.
