Converting to GPT

Hello,
In a couple of days I'm going to upgrade my computer/motherboard to one with UEFI, and I thought I'd start with the preparations right now. I've think I've read up on most of it, but I'd like to make sure before I begin tinkering.
- I'd like to keep my current /boot, /, /home and (if possible) Windows partition.
- Since I'm going to try it out with BIOS at first, I'll have to configure without UEFI support for now.
Step 1
Create a 2 MiB non-formatted BIOS partition at the beginning of the drive, and set its flag "bios_grub"./*]
Create a ~200 MiB FAT32 EFI partition (for later use) after the BIOS partition.
Create a 2 MiB non-formatted partition at the end of the drive.
Run GPT fdisk to convert to GPT.
All this can be done without formatting any previous partitions (I have a 512 MiB /boot, so there's plenty of room to shrink/move).
Step 2
Boot up a Live CD and run grub-install (using grub2-bios), and grub-mkconfig.
Step 3 (When I have my UEFI computer)
Before removing HDD from my hold computer, install grub2-efi-x86_64. (So that I can bind mount and use it on Live CD)
Boot up using a Live CD, following wiki instructions in order to install to EFI partition. Run grub-mkconfig as well.

Just wanted to add that Step 1-2 worked great so far (booting properly).

  • [SOLVED] Converted MBR- GPT: Gummiboot installation borked

    I am converting an MBR installation to GPT, so I can dual-boot Win+Arch with Gummiboot.
    After successfully changing the partitioning, I (1) set the BIOS to boot in EFI only; (2) booted from an arch EFI installation disk; (3) arch-chrooted in, mounted /boot to the Windows EFI partition, and installed Gummiboot. Gummiboot found the Windows EFI partition and installed correctly, I believe. I next followed the Beginners Guide and created the arch.conf and loader.conf files in the EFI partition.
    When I try to boot into Arch, the bootloader reports
    /vmlinuz-linux not found
    or something similar.
    I've clearly overlooked something along the way, but I'm not sure what. Thanks in advance for any suggestions!!

    How did you go about converting your MBR disk to a GPT format?
    I first used the Gparted (live CD) to shrink the initial and ending partitions of sdc slightly. (This may have been unnecessary.) Then, I used Rod Smith's gdisk, following the Wiki.

  • Convert From MBR to GPT without loosing installations?

    Hello !
    I have windows 8.1 on a standard MBR partition.
    Is possible to convert to GPT without loosing the installations I made ?
    ( Of course the Bios support UEFI ).
    Thank you !

    Hi,
    We cannot ensure the third-party tool safety.
    For built-in tool, either using Windows interface or command line, back up or move the data on the basic master boot record (MBR) disk you want to convert into a GUID partition table (GPT) disk. It cannot remain your data.
    For more information, please read this article:

  • RAID reconfiguration and change to GPT

    Hi I have 2x HP DL 380 G6 Servers with Windows 2008 R2 Datacenter and Windows server 2012 R2 datacenter which are hyper V servers. Until now everything was fitting 2TB RAID 5 . Recently I added new HDDs and nothing above 2TB is recognized. I assume that
    it is because at the beginning I formatted drive as MBR. Now I assume that I need to convert to GPT. 
    The question is what would you do (or even better what you did and your experience in that manner) 
    Online conversion MBR to GPT with some software (if you have any proposal I would be thankful)
    Offline conversion - to delete and recreate raid format as GPT .......

    I don't think it's possible to perform an online conversion from MBR to GPT.  You are changing the structure of on-disk partitions.  Backup.  Re-initialize/format.  Restore.
    You might be able to find some third-party tool that says it can do it.  But, it's your data.

  • G500 change MBR to GPT for win8 Install without deleting the oem partition

    Hi, I just bought Lenovo g500 and it came with Free DOS. Now I want to install windows 8 64-bit.
    My HDD came with:
    1 system partition of 1000 MB (maybe Free DOS partition?)
    959 518 MB Unallocated space
    1000 MB OEM - reserved partition
    It has MBR partition table. To install windows 8 64-bit I need to use UEFI boot with GPT partition table, so I need to convert the MBR table to GPT. Microsoft suggest to delete all partitions and convert to GPT using Diskart command, but if I delete all partitions I will lose the 1000 MB OEM partition (and oneKey recovery)
    Is there any solution on how to convert to GPT without losing the OEM partition? or I have to choose between win8 and OEM partition.

    Hi Gicevgoran,
    Welcome to Lenovo Community Forums
    I’m sorry to inform you that installing the Windows 8 is not possible without making changes in the default partition created in the computer while the pre-installed OS (Operating System) was installed, I suggest you to create a Recovery discs in your computer and then make changes so that you can revert back anytime if you require, below is the link to download the User Guide for G500 Laptop and refer page no. 21 for the steps to create the Recovery Discs for the computer.

  • Cannot install windows 8.1 on imac 5k - apple support says "Correct, that machine can't install windows" Boot camp fail

    I have a brand new imac 5k, with 4ghz i7, 295x GPU, 3.1TB fusion drive.  Bought the machine so I could dual boot - I need windows for VR Dev work.
    I've spent the last week and a half on tech support calls with Apple Senior Tech agents, and Microsoft agents as well, and today have been told that indeed this machine cannot run windows 8.1.  Apparently Apple engineering knows about the issue, but says the problem is microsoft's.  Ugh.
    The latest iteration of the issue comes when installing 8.1 onto an external thunderbolt SSD (without even using boot camp) - I go through the EFI installer, convert the drive to GPT, format it as ntfs, but when I select the partition to install onto, the installer says it can't find the partition it just created.  Smuh? 
    I've also tried the install through boot camp.  This installation actually worked twice, but the install was unstable.  After booting back into osX, then returning to Windows, the windows install went corrupt and couldn't be repaired.  Subsequent attempts to install windows yielded a flurry of different errors, including "windows doesn't support GPT in this mode" or "the disk is locked, please unlock the disk" or "MBR must be converted to GPT" (where once I converted to GPT, the drive could no longer be found, despite the operation completing successfully.)
    At any rate, it's a huge mess.  I'd happily return the machine for a different config, but the company I bought it from will only swap it for a similar model -- so I've spent a pile on a machine that does not function as advertised; apple says "too bad, talk to Microsoft." Microsoft says "too bad, we've never seen this, this is an apple issue."
    Has anyone out there gotten windows up and running on an iMac5k with fusion drive?  If so, did you have to go through a crazy maze to make it work?
    Any help is appreciated.
    Thanks,
    MC

    After much gnashing of teeth, and a half dozen support calls, I'd all but given up.  I finally seem to have solved this though - sort of - by installing windows 8.1 on boot camp on an older iMac, then cloning the bootcamp disk to an external thunderbolt drive via Winclone.  That worked seamlessly, sticking to winclone's instructions, and I can boot via EFI to Windows 8.1 on the new iMac.  So far so good.
    I usually install W8.1 via EFI by using DU and a Free Space partition. The 3TB Fusion is first split into the underlying SSD/HDD physicals. OSX and Windows OSes are installed on SSD via EFI (no BCA). The OSX part and half the HDD are then used to create a new CS volume. The other HDD half becomes NTFS for non-Windows OS files. The Hybrid MBR method is completely unsatisfactory with the 3TB Fusion drive.
    How is the TB/Winclone image for performance of the OS (since pagefile.sys is also on the TB)?

  • Windows 8 Recovery

    Hi, I`m using HP Envy 15 J-126tx which came with windows 8. While using Win8, I noticed some problems, like I my graphics were not as good as they should have been, some programs were totally blurred like utorrent, chrome etc. I thought it was drivers problem, but then searching on internet, I found that people who had Windows 8 and dedicated graphics memory were suffering this problem, and personally I thought windows 7 was more stable and a perfect window for any kind of user, so I tried to install windows 7, and in doing so, I got my hard disk cleaned, as I had to convert my hard disk from GPT to MBR in order to install win7. Now I`m using windows 7 with SP1 64-bit, but still after installing all latest available drivers, I haven`t got what I was expecting, e.g.
    1) Graphics problem is still there, blurred and fuzzy text on some apps like chrome, utorrent, and any installer window etc
    2) Wifi mac address can`t be changes using options (Locally Administered MAC Address)
    3) Bluetooth driver does not install, I tried several drivers, and there are no official drivers for Bluetooth on HP Support (if there are any, kindly share the link with me)
    4) FingerPrint reader does not work. (I`ve installed drivers, but HP SimpePass does not function)
    Now after having so many problems still there, I want to get my windows 8 back, as I can`t claim any warranty using Windows 7. Then I would go to the retailer and ask him to solve the graphics problem.
    The problem is, in converting from GPT to MBR, I got my hard drive cleaned, so I can`t use recovery that came along with my PC.
    Is there anyway I can get some recovery disk? or Recovery ISO image?
    or my friend has also same laptop and he hasn`t removed his recovery drive, and he is using Windows 8, can I use his recovery? How?
    I cant see his recovery drive in My Computer, I can see recovery disk only in Disk Manager which doesn`t have any drive letter associated with it. Can I use this recovery drive? How can I make an ISO image of that drive?
    I can buy a new windows 8.1 key from Microsoft if I need, all I want is already installed drivers and softwares that first came with my laptop.
    I hope HP does not disappoint me this time, as I`m already not satisfied with the product graphics and drivers support by HP.

  • Error when try to install windows 8.1 from UEFI USB

    Hello !
    I have prepared a UEFI USB flash drive installation for Windows 8.1, as described in this link :
    http://www.nextofwindows.com/how-to-make-uefi-bootable-usb-flash-drive-to-install-windows-8/
    The computer is on UEFI mode.
    Now the computer boot from the USB flash drive, but after some seconds, I get an error message on a blue screen:
    Your pc need to be repaired
    The application or operating system couldn't be loaded because a required file is missing or contain errors
    File \windows\system32\boot\winload.efi
    Error code :0xc0000359"
    It’s strange because the hard drive has no partitions, and the USB flash drive doesn’t have a path path like
    \windows\system32\boot\winload.efi.
    What is happening and what should I do?
    Thank you !

    Hi,
    When install Windows on UEFI mode, you need to convert your disk to GPT firstly. Therefore, please check if your disk was already converted to GPT partition style.

  • MacBook Pro is not recognising my WD my passport external Hard drive

    PLEASE PLEASE HELP
    I have 200GB+ of data on my HDD and I DO NOT WAT TO FORMAT IT
    I partitioned my WD my passport external Hard drive on Mac through Disk Utility
    i then plugged it in to a windows XP computer
    and when it did'nt recognise it i went to
    right click My copmuter > Manage > Disk management > then i right clicked on the hard drive's name > convert to GPT disk
    i though by doing that windows will recognise it .. it didnt
    BUT .. when i reconnected it to my mac thats what i got
    it still shows in my disk utility but all the options are greyed out
    PLEASE if someone knows a way to fix this i'd really appreciate if you would tell me
    i have really important documents on that hard drive
    Thanks you in advance 

    I have fears that you data may be gone.
    Did you try to see if you could access data on the Windows PC?
    I am not versed in Windows but based on the steps you describe suggests that you formatted the disk and erased it.  What you might try is to look for recovery software and see if there is anything to salvage.
    Ciao.

  • WS2008 R2 - Invalid dynamic disk

    I have a software RAID5 array in Windows Server 2008 R2.  5x4TB drives.  After clean shutdown all the disks in disk management are listed as invalid.  When I try to reactivate any of them I get this error message: This operation is not allowed
    on the invalid disk pack.
    What can I do?  I've searched high and low and can't find a solution.

    Hi, 
    Based on research, it seems a bug that Dynamic disk(s) comes back as INVALID after taking offline, or following reboot. 
    This bug surfaces when the size of a record in the LDM matches exactly the size of a block on disk. In this situation, volmgrx incorrectly flags the record as incomplete. After reading the whole database, volmgrx will clean all incomplete records. That’s why
    we end up with an empty volume record and with a plex that’s not referenced by a volume. 
    In this repro, we have a record for a volume that’s bigger than 2TB, has a 3 digit number and has no drive letter (which means attributes are stored in the record). Because of this, the record size was exactly 68 bytes, which is the size available in the block
    after all the headers.
    If the effected Windows 2008 R2 server is Non-DPM server, we must re-create the volumes manually and restore from backup. 
    If the server is a DPM 2007 server, all of the dynamic disks in the DPM storage pool will be inaccessible. To avoid having to rebuild the DPM server from scratch, you can use the following procedure to clean (wipe out) the dynamic disks and recreate the DPM
    replica and recovery point volumes while maintaining the rest of the DPM 2007 configuration. 
    WARNING: This procedure is non-reversible, and will result in ALL replica and recovery point volumes to be permanently lost. Verify with the customer that he has a >2TB volume configured before proceeding. 
    1) Run diskpart.exe - and issue a "list disk" command - and see which disks show the status of INVALID 
    2) Select one invalid disk at a time and issue a CLEAN command to wipe it out and make it a RAW disk again.
    3) Select one disk at a time and convert to GPT, then Dynamic. 
    4) Exit diskpart.exe 
    5)Now add the same disks to the DPM storage pool under the management tab - disk tab. 
    6) From command prompt - run the following command to remake the DPM volumes - this may take hours... 
    dpmsync -reallocatereplica 
    7) AFTER Dpmsync completes, re-run diskpart.exe and save the output of the "list volume" command. 
    NOTE: Make the DOS window so if has a height of 9999 before running list volume - then copy the contents of the window to notepad. 
    8) Search the output of list volume and locate any volumes are larger than 2000 GB (2TB) - note the mountpoint path. 
    9) From command prompt - run mountvol.exe >mountvol.txt - then open the mountpoint.txt using notepad. Search for the path for the >2GB volumes to get the volume {Guid} 
    10) Use mountvol.exe to assign a drive letter to that volume. 
    mountvol E: \\?\Volume{bf14e9ca-d929-11dd-8f76-806e6f6e6963} 
    11) Repeat steps 7-9 for ANY and ALL volumes that have a volume numbers above 99, and exceed the 2TB size. 
    It is now safe to reboot and not experience the dynamic Invalid status for the dynamic disks. If the customer creates any more dynamic volumes that exceed 2TB - they MUST assign a drive letter or they will experience the same issue. 
    12) Run Consistency checks for all the data sources to get the DPM server back into a consistent state and continue protectecting the production servers.
    I hope this helps.

  • Can't find partitions on external HD

    I bought a 4TB Seagate Backup Plus, removed the disk from the enclosure and connected it directly into the motherboard.
    I believe it was using MBR (can be done because it has 4096 bytes per sector) but I changed it to GPT and created 3 new partitions with cgdisk: http://i.imgur.com/IRllfPj.jpg
    After almost 20h copying all my files, I put the disk back in the original case and connected it through my USB 2.0 port.
    The problem is that the computer doesn't seem to recognize the partition table when I'm using this enclosure: http://i.imgur.com/kRCvC5t.jpg
    I connected it again to the motherboard and everything still working alright.
    I don't know if converting from GPT to MBR is going to solve the problem, I'm afraid to lose the 3rd partition: http://i.imgur.com/5xBUdVI.png

    cfr wrote:You said that it has 4096 bytes per sector but you partitioned it in gdisk with 512 bytes per sector. Once back in the external enclosure, though, it is showing 4096 bytes per sector again. Could this be part of the problem?
    I believe it's 4096 bytes fisical and 512 bytes/sector logical.
    I have no idea why it's showing "Logical sector size: 4096 bytes" in the second image though.
    The number of sectors is correct: 7,814,037,168 * 512 = 976,754,645 * 4096
    Edit:
    I won't create more than 4 partitions (only 3). So I believe that's not a problem for me.

  • Laptop Partition Concerns - SOLVED

    Hi there,
    I'm going to be installing Arch on my laptop (well aware of the minefield that is closed hardware and an ATI dual graphics card) alongside windows 7 as there are some features which are not as well implemented; editing .NEF files, for one! Cursory defence of my maintaining a windows partition over, now I get to the real issue;
    The laptop I have is an HP, and as such the hard drive come with 4 partitions already on the disk, these being
    SYSTEM,
    C:
    RECOVERY (D:)
    HP_TOOLS
    I've already freed up some 100GB on the hard drive to accomodate the Arch install, however, I'm led to believe that you cannot have more than 4 primary partitions, and all of the above are primary. As I was planning to have 3 linux partitions;
    swap
    /home (with symlinks to C:\user\ to make up for a lack of space)
    I'm aware that I can delet HP_TOOLS with little disruption to my windows install, but that still then only leaves me with one free partition on the hard drive (I've been led to believe), so I wouldn't be able to have a separate /home partition from my root partition?
    If this is too poorly written, or I've missed any similar posts, hopefully I can clarify or be redirected! (I'm not a total newb re: disk partitioning, however, it will be the first time I've dual booted from the same hard drive, rather than having 2 HDDs, one for each OS!)
    Thanks

    To be perfectly honest of there were any serious faults with windows I have no problems just reinstalling it (I own a legal copy which I had installed on a desktop pc just after W7 was released) which would also mean I would be free of HP bloatware which comes as default. As far as I'm aware I can get around not having the HP_TOOLS by using some HP software to make a copy of some of that stuff on DVD or what have you.
    As far as partitioning goes, it seems to make more sense to convert to GPT rather than faff about with different types of partition (at least to me, although using GRUB2 might pose a few issues with that, but fortunately the wiki seems pretty exhaustive on that matter - one of the reasons I feel safe about trying out Arch!)
    @Perbh I've had that happen before, admittedly with ubuntu systems a while back, and it never seemed too much hassle to just reset it all from a live CD or a system recovery disk based on linux, so I don;t mind too much about that! I've had more issues not being able to boot windows alongside linux (after a fluffed linux setup messed up the boot manager, and then windows couldn't figure find ANY of the partitions, although THAT was fixed by use of a recovery CD (I have my windows 7 install disc to hand, so no worries there either, really).
    My only misgiving would be that changing to a GPT rather than the MBR would make life a lot more complicated when installing grub2, as I would be inclined to do, since it's more up to date software, although as far as I can tell it's not overly complex going by the instructions from https://wiki.archlinux.org/index.php/Gr … structions, I just have to be careful when I'm partitioning! Which, to be honest, I would probably do prior to running the Arch install, just to ensure I have the partitions where I want them on the disk, to end up with something along the lines of;
    [SYSTEM]  [C:]  [REVOVERY]  [D:]  [HP_TOOLS] ¦ [swap] [EF02 for GRUB2] [/]  [/home]
    Hopefully this would still allow me to still boot windows, and then install Arch (with grub2) on a GPT (assuming I got the theory right as far as grub2 on a BIOS-GPT install)
    thanks all for prompt aid!

  • Hp all in one 19-2013w and 19-2113w , that in the Bios i am not getting the legacy support option

    i want my system to be boot from the USB Drive - but Legacy support is not avialable in the Bios and that i why in the boot menu i am not getting my USB option Model no : Hp all in one 19-2013w and 19-2113w   

    Same here. My computer was "born on" Aug 13th, 2014, so today it's exactly only 2 months old. Since Windows 8 was so sluggishly slow i decided i was going to wipe the drive and install Linux. I had already been successful doing the exact same thing with a new HP laptop about 1 year ago.. it also was a Windows 8 preloaded machine, so i am very aware of the UEFI "Secure Boot" methodology and what it took to disable secure boot mode and enable legacy mode. I am happy to say that laptop ran Linux beautifully and without any issues. So now, i have the HP AIO 19-2113w machine preloaded with Windows 8.1, which has been wiped. I have converted the GPT to MBR and attempted to disable secure boot mode and enable "legacy mode". The Legacy mode option says i must first disable secure boot mode, which i've done several times. (When restarting after doing so, i get a prompt to type in the 4 digits on the screen and press enter, which i've done several times now). Going back into bios after doing this... i STILL can't get past the "You must disable secure boot mode before using this option... blah blah.". So i decided to look up if there were any lawsuits against Microsoft and/or HP reguarding UEFI bootloading issues, and there are. Right now i am sitting on a 2 month old computer with NO operating system and no recovery partition. The money i spent on this computer could have gone towards a different brand, such as an Asus which has never given me trouble. You guys need to contact me ASAP with a fix, or you'll get plenty of free negative advertising.

  • Reverse Scrolling of G580

    Hi Guys,
    Just got a new G580 Lenovo and im already getting headaches.
    Im assuming thanks to windows 8 the scrolling has turned "natural" and decided to reverse itself which if i didnt have to use many different PC's for work id just plain suck it and get used to it but i can see myself getting irritated at forgetting when i should be reverse scrolling and when i shouldnt.
    How can i disabled this? I've checked the standard Synaptics settings and i get the option to have vertical scrolling on, or off. Thats the extent of the settings i get.
    Its using Synaptics Touchpad V7.5 (Driver version 16.2.10).
    Link to image
    And whilst im posting, has anyone successfully installed windows 7 on a default pre-installed windows 8 laptop?
    After giving up on getting the machine to attempt to boot from CD i got a Windows 7 Enterprise CD onto a bootable USB however only to find that the OS partition is GPT and not MBR (So the install threw a fit and said no). Without trashing the entire drive from another machine has anyone formatted the _OS partition and managed to get windows 7 on it? Dont really want to wipe the entire drive as ill lose the recovery partitions.
    Cheers guys and Merry Christmas!

    Reverse Scrolling is a feature on certain Synaptic Touchpad Device, if you have already tried to install the Touchpad Driver v16.2.10.3,try to upgrade the Synaptics Touchpad Driver to v16.2.1. If it doesn't work, disabling this feature is not currently possible (unless you uninstall the Touchpad driver itself and use the windows generic driver)
    In downgrading Windows 8 to Windows7, you will need to convert the GPT partition to MBR in order for you to install Windows 7. There are tools on how to convert GPT to MBR without losing data, check the following:
    1. Gdisk, discussion here.
    2. Disk Management Tool, discussion here.
    For all other, the general way to convert GPT to MBR is this guide.
    Goodluck!.
