Setup Installation :: EFI System Partition Missing Files - Repair Disk Won't Boot?
Nov 30, 2013
While I was messing around with my laptop, I decided to add on a fourth operating system, Arch Linux. I suppose I was pushing my luck a bit . Anyways, during the installation, I accidentally deleted the EFI system partition from my laptop, which contained the Windows Boot Manager and necessary files to boot. Great. I only made things worse by trying to troubleshoot, and broke grub as well.
I have a Windows 8 repair disk I made using the Windows 8 built in utility, but it does not boot: the computer turns on, and just hangs at the Toshiba splash screen.
I also can obviously not access the Toshiba recovery partitions, as they are booted into just like Windows itself.
I found a bootx64.efi file on one of my system's recovery partitions (Toshiba seems to have some really complex system going on) and placed it in EFIootootx64.efi. According to this site, FGA: The EFI boot process., I need to place the bkpbootmgfw.efi (on my system, that was what it was called, but I suspect boot-repair (ubuntu tool) messed something up when I was first setting up grub and the ESP and the bkp stands for backup) back onto the EFI System Partition.
Where to look for in the various Windows Imaging Format .wim and .swm files I have laying around my recovery partition(s) in order to extract the necessary EFI files. Any Windows Repair iso that works.
when I upgraded to Win 8.1 it was online. I have a win 8 disk but its not recognised. How can I reinstall win 8.1 and not lose anything as it reports missing files.
My daughter plugged in her ipad which normally opened in a setting which no longer works, instead opening in windows which it should not. I opened a file this morning and it opened in the wrong directory??
I was having a problem since my computer shows "windows cannot delete the active system partition on this disk". How to delete the partition on which i have windows 7 installed.
I recently did an update of my machine from Windows 8 to Windows 8.1. The update process did not show any errors or warnings and by the time it finished I was under the impression that everything went smooth.
After the update I was testing the environment and discovered that one of my desktop applications stopped working, I went to the developer's website and indeed I found there is a known issue with their software on 8.1 and to solve it, I had to completely uninstall the software and then install it once more. So I went to Programs and Features in order to do so and to my surprise the Uninstall button was missing from the interface. Right-clicking an item and selecting uninstall from the menu gives a warning message suggesting that the application might have already been uninstalled and asks if I wanted to remove the application from the Programs list. However, clicking OK or Cancel just closes the message box and nothing happens.
So I went and tried to Refresh My PC; Once I clicked Refresh My PC the verification process started and indeed it told my that some system files are missing and that it should take care of it provided I insert my Windows disc. Now since its an OTA update from Win 8 to 8.1 I thought that MS knows that some people will not have a physical copy of 8.1 and so I inserted my Windows 8 Pro System Builder disc hoping it would work, but sadly as you might have guessed, it did not. It told me that I needed the 8.1 recovery disc.
Now I have been looking everywhere for a recovery image to download and use to fix my problem, everywhere I go it suggests that I make my own copy. But how am I supposed to do that if my Windows is faulty and has missing files. I really don't wanna go back to Windows 8 and re-upgrade to 8.1. I have a monitored internet bandwidth and I cannot go and download the 3 GB 8.1 update once more.
How can I repair my 8.1 machine?
I came across this article describing how to get an ISO image for 8.1 with a Windows 8 product Key. However, entering my Windows 8 Pro System Builder (OEM) key in the box fails and tells me that the key I entered is not for this product.
I have moved my boot files to the "C" drive using EasyBCD. In so doing, is it now safe to delete the System Reserve Partition? I realize it does no harm the way it is but I have no intention of using Bitlocker and I have a recovery disc. So, to me, it serves no purpose and I'd like to get rid of it.
I have win 8 pro installed & two HDDs with two partions each , I want to migrate the boot partition to another partition on the second drive .
It would have been easier if i would have just cloned the complete drives but one of the partions on the 2nd drive has data which cannot be deleted .
So I have Drive
1 - Partitions C: ( boot partition ) & D:
Drive 2 - Partitions E: & F:
I want to remove Drive 1 from my PC so i want to copy C: to E: then remove drive 1 & boot from E:
I tried "Easeus todo backup" , did not work, it does not make the copy bootable , to make it bootale the whole drive has to be copied .
I tried making an image of C: using Windows 8 inbuilt backup feature then removed drive 1 , installed Windows 8 on E: then tried restoring the image of C: but i got some error.
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 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.
Is it possible not to have the partition "recovery"?
Because if you look at the two tutorials:
- UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums
- UEFI (Unified Extensible Firmware Interface) - Install Windows 8 with
In the tutorial to install Windows 7 in UEFI, there is not that damn partition recovery, while in the tutorial for Windows 8, we can see it.
When I install Windows 7 (MBR mode), I avoid this partition "recovery" by creating a partition with a name before installation. I install the OS on it and everything is fine, no partition "recovery" But here, since one must delete all partitions, If I create a GPT disk with a partitioning tool before installing, is that it might be appropriate?
I had my system set up for Dual boot (on separate hard drives) for both Win 8.1 and Win 7. Win 8.1 developed a problem and unfortunately the only back up I had (my fault) was for Win 8 before I installed Win 7 and the dual boot.
I reinstalled from the backup and then updated Win 8 to 8.1. Both the Win 8.1 64 bit and the Win 7 64 bit work OK but the dual boot is now missing in Win 8.1.
Is there any way of repairing/creating the dual boot, either in Win 7 or Win 8, without using BCD Edit?
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 am trying to do a clean install of windows 8 on my laptop (Elitebook 8770W) from a USB stick with original MS Windows OEM iso. Once I boot from usb stick, at the setup screen I enter the product key and then choose advanced to do a clean install. I then choose my hard disk partition to install windows but I get stuck here with this error:
"Windows cannot be installed to disk 0 partition 1"
I deleted the partition and choose to install on the unallocated space (150GIG) But still get the same error and when I click on the error this is what I get:
"Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's Bios"
In bios I have my disk set as Raid and I also have a m-sata Flash cache. If I change raid to AHCI I will be able then to install windows. But if I turn it back to raid after install I will no longer be able to boot I have to be in raid mode to use my m-sat as cache drive.
So here I am stuck not being able to install windows I even downloaded latest intel rapid storage technology drivers and put them on the usb stick with windows setup files. When i got the error I choose to load driver. But even after that I was getting same error and windows would not install on my HDD.
What's the right way to install in this condition (raid)?
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 did a Clean Install on a new SSD Drive. When I tried the Relocate User Profiles to another Partition, the System gave me a message that I would have to re-install, but the Windows 8 CD will not re-install. What can I do?
So I did a disk repair for one of my hard drives (not the system drive ) using check disk because I could not open my folders it would say they were corrupted. This followed me powering off my pc while it was shutting down. So after the chkdisk repair my drive was now functioning ok except for one thing; some of my files and were missing. I could not see any Found.xxx folder even after showing hidden files. I then checked my free space and noticed that it had not changed inspite of the files missing one of which was a folder containing 250GB of data which I cant afford to lose. This has led me to think my data is still on the drive but just hidden somehow. How can I recover this data.
I got windows 8 online and I went to try and use the re install feature but its prompting me with this "Some files are missing. Your Windows installation or recovery media will provide these files" But since i got it online I don't have the CD but I do have the product key
I'm trying to recreate win 8.1 pro system reserved partition on my ssd. Initially I installed windows on my ssd (c: ) and windows created the sysres partition on my unformatted hd (without telling me anything). After some trouble I managed to be able to boot from ssd directly without going through the sysres partition on the hd. Now if possible I'd like to recreate the sysres on the ssd (by disconnecting my hd so that windows has no other options than creating this on the ssd). If a try a system refresh it tells me it would wipe away all my user installed apps.
I tried to install 32 bit Windows 8 in my friends laptop through bootable usb. It has win7 preloaded. I tried for the dual boot. But when I select the partition drive it said that windows cannot be install in that drive because the selected drive is GPT partition style. How to install Windows 8 os in that GPT partition style hard drive.
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.
Ok so i am trying to install windows 8 X64 onto a different hard drive as windows 7 so i can switch between the two at startup.Ok so my problems started yesterday when trying to install windows 8 onto the Hard Drive i was getting"Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks."To fix this i converted the disk to a GPT disk in Disk ManagerNow im getting the Error "Setup was unable to create a new system partition or locate an existing system partition. See the setup log files for more Information." Here is a screenshot of disk manager at the moment.I am trying to install Windows 8 to Disk 2.
I already have windows 8.1 installed in c: partition
I have created new partition ''New Volume :" to install windows server 2008 on it ,but when I try to boot from the CD to install it this message appear
"Windows cannot be installed to this Hard disk space . The partition contain one or more volumes that are not supported for installation" ...
Here is the deal I have 2 hdds (160 gb and 1 tb) late last night used the 1 tb as a flash drive and re installed my OS on the 160 gb drive. The "system" files are on the 1 tb drive and all other files ( boot crash dump etc ) are on the other one.
PROBLEM: while doing a cold start the system fails to spin up th bigger drive in time for the software to detect the system file on the bigger drive and it brings up the boot manager saying files are not present to load, a restart fixes the problem as the bigger drive would be up to speed by then, any work around to delay the boot till both drives are up to speed .........???.
Further i think that moving the "system partition " to the other disk will eliminate this issue ...... how do i go about doing that ... See the image below
QUESTION :if i remove the 1 tb disk physically and reinstall OS and connect it back will everything be as good as new or will it pose problems as then there would be two "system " partitions .....
Alright, so after restarting my Toshiba Satellite L50A16H Laptop (Windows 8.1) it gave me a blue recovery screen,
it stated: The Boot Configuration Data file is missing some required information. File: BCD Error Code: 0xc0000034
Unfortunatly I haven't made a backup or recovery file to boot my computer from so I'm stuck with the issue of finding a windows 8 iso file that matches my system, i tried getting the windows 8 iso from microsofts website but it asks for a product key before it lets you download the file, the problem is that my product key is built into the laptop and Toshiba has not provided me with the key on a sticker on the bottom or through any other method. apparently its built into the BIOS. i have a 16gb USB stick that i can boot from. using a key finder is obviously not an option because i cant start up the laptop. I was also wondering if i manage to find a windows 8 iso file to boot from, will my toshiba laptop automatically fill in the product key for windows 8 as i dont have it.
I want to install Windows 8 Pro onto the second partition of my laptop that already has W7 Pro installed. What are the correct settings for the second partition(simple, active, primary,etc) so that the existing System Reserved partition used by W7 won't get clobbered? Is this even possible?
I'm trying to upgrade from Windows 7 to Windows 8 (and then 8.1) on a laptop with a 240 GB SSD. When I run setup, it loads, but then says Windows can't be installed because there isn't enough free space on the system reserved partition. My reserved partition is only 32 MB (I believe it was shrunk from 100 MB when I swapped the SSD in).
Is there any way I can resize the reserved partition and install Windows 8, or will I need to totally reformat the drive and repartition? Don't want to reinstall all my software .....
I have a custom PC I built and I was running 8.1 on it. I have to drives a 120gb ssd that had windows on it and I have a 1 TB that had the 350mb system reserved partition and 2 other partitions I had for data and a boatload of free space. I wanted to try and install Linux Ubuntu on the 1tb hard drive. I did a custom install on it because I didn't want it to delete my existing partitions so in the install I made 2 partitions for Ubuntu, after I installed it my 2 data partitions are gone and I don't know what happened with the 350mb system reserved partition.
On that disk now is the 2 Linux partitions and a 150mb partition that I can't tell what it is. But now I can't boot into windows, even when I go from bios. My question is in that system reserved partition is that where the bootmgr is? Because I did nothing with the ssd where windows is and I get a no operating system error when I try to boot off it. How I can fix that disk if the system reserved partition isn't on it.
Lenovo g505 History - What I did so far, is further down Computer went badly wrong and would not Boot into Windows (belongs to my mates 11 year old) I decided to a Factory Restore it seemed the best Option as my knowledge stops, til now, at Win 7 I did it, but it doesnt Boot into Windows CURRENT I have the HDD connected to another computer which is running Win 7 I can now see that it did indeed do a Restore to the System Partition Pic Shows Disk in Disk Management

PDF of the 3 Pics - easy to read detail
In Disk Management I see 7 Partitions Now I think I understand what the Problem is - ?too many Partitions? But I dont have a clue how to Resolve it correctly My inclination is to Run DiskCheck from Win7 on the HDD but I am not sure if that will work on Windows 8? same with FixBoot if it is Possible? The LENOVO H Drive has 3 Folders with Data in it Lenovo & Drivers & Applications
HISTORY I did the Restore took 3 hours but then said Success Option to Reboot or Shutdown Chose Reboot eventualy Booted to a Windows Pale Blue screen with the Cursor half hour later, the Box came up to start the Restore again I did it, same as above time and Result so this time I chose Shut Down Started - Logo for long time then loading Files and back at the Box to Start Restore again
I have since tried booting with Default Options UEFI and Legacy in the BIOS In the middle of all this, as it is about 4 hours to do the restore.
