After Partition Changes, 0xc0000225 And Cannot Boot?
Mar 6, 2010
So i had two partitions on a physical disk, and wanted to delete the first and enlarge the second. I usually use gparted off the ubuntu live cd because it completely separates itself from windows details and allows a lot of disk changes in one interface; no conflicts. I moved forward with my changes and rebooted the computerI now find myself standing at this boot screens with error 0xc0000225 and a "corrupt" /boot/bcd file. Googling that information, the first hit was a solution about using gparted and getting this error. I thought perfect, but going through the steps, i still have no resolve. I have now been in and out of every boot problem thread on the internet and cannot figure it out.I have tried: windows 7 repair startup tools- rebuilding the bcd from scratch- bootrec /fixmbr and /fixbootWhen i boot into ubuntu or repair mode, i can browse the file system fine. can see the /boot files, create a new bcd file, and so on. One thing to mention is every test i have tried yeilds the same consistent error. The error has not changed whatsoever. My assumption is not that the /bcd file is corrupt or configured wrong (as the gparted solution/post suggested)

So basically I have two partitions: Vista C: and Windows 7 D:, boot file is on C:
I had installed Jolicloud OS on my computer and it carved out a drive from my Windows 7 partition. later on I EasyBCD to remove grub when I figured out that it will be a pita to get my wifi working. afterwards i booted from the jolicloud installer, then used Gparted to extend the Windows 7 partition back to it's original size. i then rebooted, and it ran the disk repair, but now Windows 7 won't boot, giving me:
0xc0000225
"Windows did not start correctly. A recent hardware or software change might
be the cause.
If you have aWindows installation disc, insert the disc and restart your
computer. Click system recovery options, and then choose a recovery tool.
(Startup Repair, available in some versions of Windows, can automaitcally
diagnose and fix startup problems.)
If you do not have this disc, contact your system administrator or computer
manufacturer for assistance.
I've tried to use the recovery feature on my disk, but it cannot see my hard drive and it's not able to locate a driver.
help? Windows Vista is AGONY
also: Easy BCD whe running from Vista says:
There are a total of 2 entries listed in the Vista Bootloader.
Bootloader Timeout: 10 seconds.

I'm a long-time reader but new poster. I am currently running Windows 7. I want to install Windows XP onto another disc and have a dual-boot setup. I keep Windows 7 up to date and secure, but for the XP partition, I would rather not have antivirus running or even installed, in order to limit background processes. I will not be logging into any place or making any credit card purchases when booted into Windows XP. It will just be used for surfing, games, etc. Further, if and when XP becomes compromised or buggy, I will simply overwrite the partition with a backup image.
If I use Bitlocker to lock down the Windows 7 partition (with the encryption key on a thumb drive) and boot into Windows XP, am I correct in thinking the XP installation see or can't access the Windows 7 partition? If XP gets compromised, can a virus access or write to the Windows 7 partition?
Is there any other reason why this would not be secure? Can a virus write to the BIOS?

I have Windows 7 ultimate 64-bit installed on DELL desktop (Optiplex 990) i7 Core. I have two HDD: Disk 0 contains the operating system 500GB. and Disk 1 empty 1TB.
I want to make a partition on disk 1 to mirror the operating system partition and keep the remaining for data storage. I tried to do but I had the following error message: "All disks holding extents for a given volume must have the same sector size, and the sector size must be valid."
I tried to attach a screen shot but couldn't.

After successfully restoring the Windows7 image from partition 2 (/dev/sda2) to partition 1 (/dev/sda1) using Clonezilla, Windows7 is no longer able to boot and displays the following error messages:
Quote: Windows Boot Manager
Windows failed to start. A recent hardware or software change might be the cause.
[...] Info: The boot selection failed because a required device is inaccessible To solve this particular issue, I rebooted with the Windows7 DVD and hit Repair... which didn't work. But even if it did, I can't do this every time I restore an image to test. Note that I used the same laptop to save and restore the partition, so it's not HAL-related.
Here's what the Repair screen says (poor man's screenshots): Attachment 201071 Does someone know what can be the cause for this error, and what can be done before saving and/or restoring an image with Clonezilla?

I got a dual boot with GRUB2, Arch Linux + Windows 7 Pro x64.Always used it with no problems, and now the Windows loader can't work.I only managed to read the status value, 0xC0000225, and something like "boot manager generic failure", "a required device is inaccessible".I tried using the repair function from my full retail dvd, but it didn't work as well. I think it's because it acted on the windows partition, while the windows boot is stored in another partition of about 100mb, wich was created automatically during the dvd installation.So I guess the solution would be giving to the repair function the right drivers to let it "see" the boot partition, but how?
My system specs:
Windows 7 Pro x64
Full Retail
The machine is a laptop, 1.5 years old
OS installed a few months ago

my computer, a toshiba satellite L655D-S5159, has been broken recently. At first, I got an infinite startup repair loop, because of a corrupted registry. I checked the registry files and they are all 256kb. I tried to run sfc /scannow and chkdsk /f /r, but that didn't do anything. Then I tried to run bootrec rebuildbcd, and now I'm getting error 0xc0000225 at startup.

I have a Boot Camped Mac Mini with Windows 7. I recently needed to allocate more disk space to it as i only had a gig left, i booted into MacOS and used Disk Utility to make the Mac partition smaller, i rebooted into windows and downloaded software called 'Partition Wizard' from www.partitionwizard.com. I dragged the Windows partition all the way so that it used up all the Unallocated Space, it required a reboot to finsih and when it did it displayed an error such as thistatus:0xc0000255Info: The Windows Boot Configuration Data file is missing required informationI have the Installation Disk and i have tried repairing more than 3 times and it seemed to do nothing, so i tried using the CMD and bootrec.exe and now when i start the repair wizard it says there is no windows partition yet i can still try repairing things (Yet still does not repair anything). I downloaded EasyBCD but im on my Mac partition right now and its an exe, i have no clue how to run that within windows to try and repair the Bootloader. I do however have access to the BOOTCAMP partition through the mac side, and i can access all the files. Is there some way i can repair the bootloader through this?

System has XP pro and Vista installed, single hard drive (with 3 partitions, XP and Vista each on their own partition, 3rd partition is for data) Removed existing hard drive Installed brand new hard drive Installed Win 7 ultimate x64, works great Installed original hard drive (the one removed in step 2) So now, system has BOTH hard drives in it. Boot up, only XP/Vista boot menu appears (I can boot to XP or Vista, but not WIn 7) Also, when booting to XP with both drives in, the new drive with Win 7 shows up as Disk 1, with original disk as Disk 0.

I initially installed Windows 7 Pro 64-bit along side my Windows XP 64 bit on two seperate hard drives. What I'm trying to do is remove the drive that had XP on it and put it in my other system to do a fresh Raid 0 Windows 7 setup. But when I remove the XP drive, it wont boot into Windows 7. I'm fairly sure that Windows 7 rewrote the XP bootsector and so without that drive it wont boot. Can I recreate it on the Windows 7 drive?
I've tried the recovery stuff on the DVD, including all the command line tricks in the tutorials. When I go into the recovery mode, it doesn't even see my Windows 7 installation. However, in Command Prompt mode, i can browse into the hard drive, and see all the windows files.
What can I do without a fresh install?

I currently have Windows 7 64 bit installed in two partiions:C: drive and E drive. Everytime I start, windows from the C: partition automatically boots. How do I get the Windows from E drive to boot? Ultimately I'd like to use the windows from E drive (which has all my installed software) and delete the one from C: drive. The problem is that I installed the one on C: drive most recently. (Long story short, I tried to delete and old version of windows unsuccessfully, and had to unmount and reformat the partition.)When I go to System Configuration under the Boot tab, I only see Windows in one partition (C: drive), so it won't allow me to delete that.

My sister just got a new laptop with 7, then accidentally installed a friend's version of 7 on top of it, thinking it was Microsoft Office. I'm trying to restore to factory settings so she doesn't lose all the software that came with the computer.
I know the recovery partition is on the computer (I made it appear by assigning it a drive letter). But I cannot boot from it (or whatever I need to do to access it).
I have tried the following:
1) Advanced Boot Options -> Repair -> System Image Recovery: no system image
-> System Restore: no restore point
2) all possible F# keys at startup, including F10 which got me to Edit Boot Options, which seemed hopeful because it named the partition number, 3, but did not allow me to change it (the recovery partition is 2).
3) F2 -> setup (nothing there)
4) burning an iso of Windows 7 recovery disc, which just gave me the same repair tool as in the 1st attempt.
5) setting the recovery partition as "active" (in fact, I think it was already active).

I normally run Windows 7. Today I decided to try out Windows 8 as well. I went into Disk manager and created a partition. I then booted off of my Windows 8 DVD and installed it on that partition. Now, my computer is only booting into Windows 8. What I really want is an option to choose which OS to boot into, but I would really like to be able to get back to Windows 7.

I have two questions:
I am running Windows 7 dualbooted with WinXP, everything works fine. I want to get rid of the XP partition, and keep the Windows 7 one only, but there is a problem. THe partition on which XP is installed is set as system and active. I've googled around but I've found no easy solutions to this. Any ideas on how to do this without reinstalling the OS?
My second question would be about the Windows 7 update: I installed the 7100 build, when it got released, but as I saw now, the latest builds are like 7200+. Are the changes updated on my build somehow, or I would have to reinstall to have the new build?

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?

I have Windows 7 on a Partition with 37.22 GB and Unallocated space with 37.31 GB. I want to extend the Windows 7 Partition to the Unallocated space. Is there any way to extend the current/boot partition? I tried diskpart but obviously that won't work I guess since I read later that you can't do it on the boot partition? Then how else are you supposed to do it?

I just recently installed windows 7 on a partition that previously had vista, and backed up my "users" folder on another partition. I copied all the files back to the 7 partition and used a program like partition magic to delete the backup and extend the 7 partition. my computer won't boot now. I've tried resetting the mbr, bcdedit, bootfix

I installed Windows 7 on my second hard drive g: (1st partition drive 1) and Windows set up a dual boot with Windows XP on the C: drive (1st partition drive 0) and Windows 7 on the G: drive (1st partition drive 1). Everything worked fine for months until I decided to dump Windows XP to try out Windows 8. I created an Win 8 installation USB FOB. I deleted the old XP Partition on C: then the install failed and I could not boot, (c: was deleted).No problem (I thought), I just swapped the hard drives to boot off my Windows 7 partition. Surprise! It won't boot either. I tried using partition Wizard to repair the MBR, from another computer. That didn't workThen I created a Windows 7 installation USB FOB (no CD drive on target computer), to see if Windows repair would take care of the problem. It could find no Windows installation. So I selected start up repair, it ran for a few minutes then said it was going to reboot, so I pressed the finish button.[CODE]

My last windows update went haywire and left me unbootable. I ran a live linux distro off an SD card to retrieve my HDD data, then decided it was time for a reformat/fresh windows 7 install. However, the factory reset process in my Gateway laptop failed a couple of times, and then the third try I would get stuck at a bootloader error and was thoroughly screwed.So I burned a Windows 7 Home Premium x64 (correct) cd to an SD card and used that to boot, formatted the HDD and installed a fresh clean Windows 7.Unfortunately the sticker on my laptop is worn out and while it's 99% legible Windows isn't accepting it. I went into trial mode, and realized I was also missing a ton of drivers and whatnot.I know that installing through the recovery partition, while full of bloatware, I get my Windows product key and proper activation, as well as all the drivers and stuff I need.... F8 into startup repair doesn't help, and instead starts a recovery process on C:, not X:.When I try Gateway's alt-F10 keysmosh it stops halfway through "loading files" and I get "An unexpected I/O error has occurred," 0xc00000e9

I have a laptop that I have set-up with 3 OS's; windows 7 (to use), windows 8 (to learn), and Linux (to do everything else). The other day I noticed a few issues and decided I needed to remove windows 8 and Ubuntu in order to prevent a system crash (kinda ironic once you read the whole thing). When I installed Ubuntu and windows 8, I created a 45gb partition for them. Not a big deal. The problem is when I removed ubuntu/windows 8 and their partition, I forgot to set something with the windows 7 partition so it was the main boot partition. Now its trying to boot from a partition on the hard disk that doesn't exist. I know for a fact that the windows partition is completely functional and intact. It's a rookie mistake and I make no excuses. At this point I'm 90% sure I need to reinstall windows 7, which I can easily do as I have restore disks and multiple back-ups. I was just curious if there is a way to change this either through BIOS or using a USB/SATA cable to externally boot and access Windows 7 system files.
