Can A GPT Boot Disk Be Converted To A Basic Volume
Feb 3, 2013
I was setting up a Win7 new build with an Asus P8B75-V and an SSD. Although I previously have done clean installs with UEFI motherboards and SSDs, this time the install DVD created a GPT volume on the boot disk (much to my surprise and which I discovered opnly after loading all the apps, moving the email, etc, etc.).
Knowing a lot more about basic MBR volumes (and how to fix problems), I would like to convert the GPT to a basic volume. I have Acronis DiskDIrector 11 which can convert the GPT to MBR, but when I tried that, it rendered the disk unbootable. (The conversion resulted in a 124MB unallocated space, followed by a 100MB FAT32 volume (!?!?!), and then the rest of the drive as NTFS.)
Is there a way to convert a boot disk from GPT to basic and have it be bootable? Is there anything that can be done with the converted HD to make it bootable?

I am building a new computer with 1TB of HDD. At first when I started to install an OS, a system volume was created automatically of 100MB size. Then I created another 200GB partition as C to install Windows 7 and 2 other partitions of 250GB. I wasn't allowed to create another one partition. After I finished windows installation, I tried to create partition in unallocated space using > New simple volume. The sytem warned me of dynamic volumes > accept it. Then eventually all 4 volumes were converted to dynamic in disk management window.

well scenario is I got my new dell 15r laptop with windows 7 basic loaded yesterday.. so backed it up and wanted to put my old PC's windows 7 ultimate version on it. I installed it, while installation it allowed to have only 4 partitions.it already had 2 partitions1) Recovery - 15gb2) something i forgot ... some 40MBso i made a partition of 125GB for OSand rest of unallocated space ie some 660gb could not be allocated in more than one partition so i let it be unallocatedso after installtion got completed and OS started i went in disk management and tried to make that unallocated space of 660GB in 2-3 partitions.but it converted all my previous partitions also to dynamic. even recovery partitions.ow do i go back to basic partitions?? particularly about that recovery partition and my C: (OS partition) ??

1) What is the major difference between Dynamic and Basic Volume It seems Dynamic volume can let you change the size of the volume up or down when there is an adjacent unused physical space, without impairing the files already stored. However Partitions (Basic Volume) can only be extended, and will always requires reformating.
2) It seems that Dynamic Volume has a lot more overheads, so it may be a little slower and actual file stored will be less, any opinion on that?
I did notice one of the Dyname Volume started to show massic missing storage space, e.g. Used Space of 30GB only has 7GB realy files on it, absolutely no hidden files there because I created the volume. This happens after shrinking and expanding it up and down a couple of time, BUG?!! If so it is a serious one.

I wanted to create a new partition to try out linux. So I decided to shrink E: by 20 GB. I then formatted the free space into a new drive by right clicking and creating new simple volume. I was warned that the drive would be made "simple", but not knowing the implications, I went ahead with the procedure. Now on rebooting, windows won't load. I had made a repair disc, so was able to use it to check for any start up errors. It reported none. Moreover I used "diskpart" through cmd to find volume c: is dynamic.

Last night as I was attempting to install Windows 8 RP to test it out, I decided I would do a dual boot incase I didn't like it. It downloaded, burned fined and I went to make a new partition, and this is where things went south for me. It converted every disk to dynamic once I had created the new disk to install it on and for the life on me I can't get it to convert back to basic, so I'm pretty well screwed if something goes wrong. Things I've done:
1) Attempt system restore - Ok, so I didn't have a restore point created so this is of no help.
2) I followed this guide found here on SevenForums and attempted all 3 methods - nothing worked Convert a Dynamic Disk to a Basic Disk
3) I downloaed EaseUse Partition master to attempt to change dynamic back to basic, and still a no go.
4) Tried to install Windows 8 again and it would not let me delete the current dynamic disk partitions to start over
5) Tried HP recovery tools to set the computer back to factory condition and it wouldn't work.
Is it possible to delete everything and start over from scratch or will it still be dynamic? At this point, i want a time machine so I can go back before ever attempting to make a dual boot.

[FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif]I initially had 1 500gb dynamic disk, with one partition containing all my documents and windows files. I created a partition in the free space to copy my documents into so I could overwrite Windows keeping my documents intact. However I did not have enough free space for all my documents so after copying over one batch of files I shrunk the windows partition and extended my document partition. I had to repeat this again so I now have three extended document partitions.[/FONT] I then put in the windows CD, formatted the OS Recovery, SYSTEM Reserved and Windows parititions but then was unable to install Windows as it did not recognise any disks. I attempted FixMBR etc but to no avail.
I searched around and saw i may be able to change the sector hex from 42 (dynamic) to 07 (basic), but im wondering whether doing so will preserve the extended partitions i have? So my question is, will changing 42 to 07 preserve the extended partitions. Do I need to repeat for each 42 (like the link you posted) and then the three dynamic extended partitions will then become one basic partition? At the moment I can not actually see the data so have no idea how to back it up? Otherwise I would do as you say and back it up, format and copy back over.

DISKPART: Acronis Disk Director (see documents spanned)
Active unDelete (again, three partitions)
HxD (showing 42)
So, basically im asking if i am safe to convert 42 to 07 WITHOUT losing any data?

I have a 500GB dynamic hard drive which had a Windows 7 install on it. I wanted to reinstall Windows, so from within Windows setup I formatted the system and Windows partition, leaving a partition containing documents and pictures (i was unable to delete them). From then, Windows seemed unable to recognise the disk so i searched in DISKPART and found that the disk was labelled as INVALID.
After Googling around it looks as though i can simply change the 1C02 in the hex from 42 to 07 - however, my only concern was that the documents i have on this drive are spanned across three adjacent (dynamic?) partitions - so i am concerned that by focing the disk to be basic i will lose the connection between these partitions.

When I am trying to partition new drive from C drive. My C drive have 450 GB Space, so wanted to make a new drive of 250 GB. Did the basic steps but when clicking on Finish I get the following error "The operation you selected will convert the selected basic disk(s) to dynamic disk(s). If you convert the disk(s) to dynamic, you will not be able to start installed operating systems from any volume on the disk(s) (except the current boot volume). Are you sure you want to continue?".

I want to shrink my C drive. The volume shrink in disk management. It says that it is corrupt run chkdsk (something like that) SO I run the error checking and restart. Then it says error can fix error (some long thing with a billion numbers. Then it says run system recovery from control panel to back date the c drive to a before hand restore. So I go through that but right at then end the last button to push it says error on c drive first run error checking.

I had 2 external hard drives connected and in disk manager I clicked delete on the wrong one? So now the drive wont show up, so I simply created a Simple volume and know it is a RAW drive? How do I recover the files there was over 100GB and some of them are really important such as records and work related stuff, it is currently a RAW partition and all the hard disk recovery softwares dont recognise it because it is a RAW drive? do i have to format it to recover the files?

I'm trying to create a new simple volume in 130 GB free disk space. There's no obvious reason why it would refuse to do so - I'm not at the hard limit on number of partitions or anything - but disk management MSC is consistently returning "Not enough space" errors. The only thing I can think of is something to do with the partition order, but if so I have no idea how to fix it non-destructively. I'm in the middle of backups on it, so deleting partitions is a no-go. At the moment I don't understand what's going on.

My computer shows Disk Volume Error every time I run system maintenance. I tried Chkdsk, disk cleanup and disk fragmentation, but it did not work. Also, my Local disk C is reporting only 8 GB of free memory. But in realty it has 17 GB free memory. Even I could not extend my disk volume through Disk Management.

Windows Disk Management utility has provided Extend / Shrink volume support.I got to knowthat FSCTL_SHRINK_VOLUME ioctl is provided for supporting shrink volume feature.I am interested to know what support is provided by File system driver and otherstorage modules to achieve shrink volume feature.Actually Linux does not have support for online shrink volume. So interested to know what are the support provided by Windows storage stack.

I've just used Windows Update to install SP1 on two more or less identical computers with Windows 7 Home Premium 64-bit. On one of the computers only the following error and warning are showing in the event viewer, from around the time the actual installation started (ie immediately after the download completed):Error - Source VSS, Event ID 12305 Task Category None:Volume Shadow Copy Service error: Volume/disk not connected or not found. Error context: DeviceIoControl(\?GLOBALROOTDeviceHarddiskVolumeShadowCopy18 - 000000000.....). Operation:Processing PostFinalCommitSnapshotsContext: Execution Context: System Provider________Warning - Source Ntfs Event ID 57 Task Category (2)The system failed to flush data to the transaction log.Corruption may occur.(end of messages)Both messages showed exactly the same time. System restore shows that a restore point was created at the same time, which suggests that it did manage to create a restore point despite the error.I tried restarting the computer, and it didn't try to run chkdsk (which I would expect it to do if there were any disk errors, and which has been mentioned on other forums). Disk management shows all disks and partitions to be healthy (before and after the restart).

I have a toshiba with a windows 7 64bit, and it's been acting really slow recently and freezing up on me so I thought there might be viruses that I needed to get rid of, so I restarted my computer so I could go in safe mode with networking to check if there really were. When I restarted my computer I momentarily forgot to press the f8 key and the windows starting screen with the logo showed up. Without thinking I turned off my computer since I didn't want to restart again (it took forever for the computer to do). Once I turned the laptop on again I ended up going to system repair. For some reason this did nothing to my computer. I left it on for hours and hours until I finally decided I wasn't going to get any results. I once again restarted the laptop but this time when I went to system repair I cancelled it and when into more options and tried doing a system restore which also didn't work and said a bunch of my files couldn't be read. When I looked back at the system repair log it said "system volume on disk is corrupt." I googled it trying to find something to help me, and every place said to run sfc scan, which I did on command prompt, which always gave me the reply "there's a system repair pending which requires reboot to complete" and since my computer can't reboot properly no matter what this is what it'll say. Is there some way to run this scan or another way to fix my computer without having to lose all my data? I have some really important files on here. I've also tried running chkdsk /r /f in command prompt which it wouldn't let me do and said it can't lock the current drive because the type of file sytem is NTFS.

I periodically create a disk image of a RAID 1 Volume consisting of two 500 GB SATA drive containing my Windows 7 system and data, and a RAID 0 Volume consisting of of three 320 GB SATA drives containing my Windows Vista. I tried to do a recovery from the disk image, but my VISTA volume does not restore. Is there anyway to restore both volumes? The recovery indicates the both volumes are to be restored, both only the Windows 7 volume is restored.

the tip to run SFC -- I'm not sure where the 'command prompt' is now in Windows 7.
What I did was search for sfc, right click, then run as administrator.
It appears something is running, but no window opened to ask or tell me anything. I checked Task Mgr and Resource Monitor and can't find anything resembling SFC, but there is activity even tho' I'm not doing anything else. The hard drive light is also flickering about once per second. What should I expect? Do I just wait patiently? How can I confirm SFC is running and fixing any errors?
