Windows Loader By Daz Unsupported Partition Table
Harold Yengo
Windows Loader is a BIOS emulator that can use some tricks to activate Microsoft products, like Windows OS or Microsoft Office, without legitimate license keys. It utilizes a series of BIOS-emulating technologies to trick Windows into activating. However, a lot of users are troubled by the unsupported partition table error when activating Windows 7 through the tool.
What causes the unsupported partition table in Windows loader? According to a survey, the main reason is related to a pirated Windows version. Besides, some other factors like corrupted partition drive, system protection service, and incompatible partition table are also responsible for the unsupported partition table Daz error.
Step 3. Navigate to the official website of RemoveWAT, download and install the app on your computer. Once installed, run the program and click on Remove WAT to start activating Windows 7.
If you are using a hard drive with GPT partition table, you may encounter the unsupported partition table in Windows loader. This has been proven by many users. In this case, you just need to convert GPT to MBR. How to convert GPT to MBR without formatting? MiniTool Partition Wizard can help you do that easily.
How to fix Windows Loader unsupported partition table? The top 4 methods have been illustrated. If you have any better solutions to the problem, please share them with us in the following comment zone.
After upgrade, upon boot, I'm presented with same, standard prompt, which asks me for password (custom prompt) though after authorization success and getting start and end partition message which normally was just prior Windows boot process starts, I'm getting another password request.
The second password prompt is different from the first one as it seems it does not read configuration file in which I have customized password prompt.
After providing for the second time same password it finds again same partition but then fails with message:
The environment is that thanks to Alex, I'm using DCS and depending on password one or other system boots. Luckily I didn't upgrade Veracrypt on second OS and upon providing password for second system it goes straight to that system without any secondary prompt for password.
What should I do next to get my system back working? I have Macrium boot image with Veracrypt incorporated driver. I've tried to prepare Veracrypt emergency ISO after v1.23Beta2 upgrade but got errors, so only have previous ISO.
That system with upgraded Veracrypt is the one hidden within partition if it plays a role.
It all seems like to me that first Veracrypt password prompt opens that container and instead of starting EFI boot Windows process, there's redirection to Dcs_boot hence second prompt for password and it doesn't see the custom prompt configuration file as is within that image?
The issue is certainly caused by the fact that the hidden OS and decoy
OS are not running the same version of VeraCrypt as there have been
changes to file naming in EFI system partition.
Update the decoy OS to VeraCrypt 1.23-BETA2 in order to have an updated
EFI system partition and after that you will be able to boot the hidden OS.
What next do I need to look at? (FYI. I've extensive Linux experience and have no issues to dump elements of partitions, etc.). With that said, I couldn't manage to mount hidden OS partition using OS booted from Linux with selected "use preboot" as Veracrypt was complaining that "partition is needed".
It looks like Dcs_Boot at main partition level instead of calling Windows Boot Manager within hidden OS it reloads/or runs another instance of Dcs_boot, though this time in context of hidden_OS maybe where the custom prompt details do not exist.
After further analysis, I was able to find the cause of the problem: the path to Windows bootloader that is executed after the password verification is coded inside the Security Region that is encoded after disk sector 62 but in 1.23-BETA the Windows bootloader location changed (from bootmgfw.efi to bootmgfw_ms.vc) and the 1.23-BETA installer doesn't update Security Region content on the disk in case of hidden OS.
To fix your problem, the simplest solution is to override the bootloader location coded in the disk using DcsProp by adding the following line to the DcsProp file (single line with space between postexec and file):
A long term solution would be to implement updating Security Region data on disk when upgrading VeraCrypt on hidden os. I'm not sure yet how much it would take to implement this. Meanwhile, I will probably add the above line to DcsProp by default to avoid such kind of issues for users who have put in place a Hidden OS.
Hi Mounir
I was happy to find your comment Today as I think this explains (almost?) the same problem Bugsy encountered.
The double login - first with customized login from decoy os and second with no customization (from hidden os).
The difference is though that I just finished creating hidden os setup on a clean laptop with beta 1.23 - so this is not a problem caused by update.
I added the line:
postexec file(EFI\Microsoft\Boot\bootmgfw_ms.vc)
to the decoy OS EFI partition, not to the hidden volume EFI partition. Probaly that is the reason - or is the configuration from first EFI partition used during the whole boot process?
I tried to get to the hidden OS EFI partition (to apply your solution there) by applying GPT table with real partitions layout and decrypting EFI partition of hidden OS but:
1. I dodn't know how to extract sec header from recue disk to file (so that I could use it to decrypt via veracrypt gui)
2. As the 4 partitions were encrypted via "oshideprep" probably that wouldn't work anyway
I was wondering if applying GPT table with real partitions layout and booting from rescue disk for hidden os (with patch applied to EFI\veracrypt\dcsprop on the USB and 1) might give me the chance to start hidden os.
I'm done for Today - maybe I can try this Tomorrow.
Do you think that could work?
Piszą że trzeba zmienić dyski na mbr. Udało mi sie zmienić 1 a 2 nie wiem jak bo na nim jest zainstalowany windows. Jestem zielony w tych sprawach jeśli byłby ktoś wstanie się bardziej rozpisać na temat jak to zrobić byłbym bardzo wdzięczny.
A wystarczy przeczytać plik readme i jak wł jest napisane, że nie wspiera ani Enterprise, ani partycji GPT. Enterprise można aktywować tylko przez KMS, a partycje GPT można konwertować na MBR lub wyzerować dysk za pomocą MHDD.
Tak mj bład przepraszam, wziąłem na szybko zdj z internetu. Ja w tym miejscu mam napisane: "unsupported partition table" Czytałem o tym, że muszę zmienić na MBR tylko nie wiem jak dlatego że na dysku mam zainstalowanego windowsa a muszę dysk usunąć żeby to zrobić.( O ilę dobrze czytałem,tak jak mwiłem jestem w tym zielony)
@up wypalasz GParted na pendrive, odpalasz sesję live-cd i tam masz podgląd wszystkich dyskw i partycji i w tym programie o ile pamiętam będziesz mgł zmienić tablicę GPT na MBR. Ale pamiętaj, że MBR jest dość ograniczona tzn obsługuje dyski do rozmiaru 2TB i możesz na nim mieć tylko 4 partycje.
This article gives some brief instructions on installingFreeBSD/i386 6.1-RELEASE, with particular emphasis given toobtaining a FreeBSD distribution. Some notes on troubleshooting andfrequently-asked questions are also given.
Probably the most important pre-installation step that can betaken is that of reading the various instruction documents providedwith FreeBSD. A roadmap of documents pertaining to this release ofFreeBSD can be found in README.TXT, whichcan usually be found in the same location as this file; most ofthese documents, such as the release notes and the hardwarecompatibility list, are also accessible in the Documentation menuof the installer.
This collection of documents may seem daunting, but the timespent reading them will likely be saved many times over. Beingfamiliar with what resources are available can also be helpful inthe event of problems during installation.
The best laid plans sometimes go awry, so if you run intotrouble take a look at Section 4, whichcontains valuable troubleshooting information. You should also readan updated copy of ERRATA.TXT beforeinstalling, since this will alert you to any problems which havereported in the interim for your particular release.
Important: While FreeBSD does its best to safeguardagainst accidental loss of data, it's still more than possible towipe out your entiredisk with this installation if you make a mistake.Please do not proceed to the final FreeBSD installation menu unlessyou've adequately backed up any important data first.
FreeBSD for the i386 requires a 486 or better processor and atleast 24 MB of RAM. You will need at least 150MB of free harddrive space for the most minimal installation. See below for waysof shrinking existing DOS partitions in order to installFreeBSD.
Depending on how you choose to install FreeBSD, you may need tocreate a set of floppy disks (usually three) to begin theinstallation process. This section briefly describes how to createthese disks, either from a CDROM installation or from the Internet.Note that in the common case of installing FreeBSD from CDROM, on amachine that supports bootable CDROMs, the steps outlined in thissection will not be needed and can be skipped.
Build a set of FreeBSD boot floppies from the floppies/ directory in every FreeBSD distribution.Read Section 1.3 for more information oncreating the bootable floppies under different operating systems.Then you simply boot from the first floppy and you should soon bein the FreeBSD installation.
If you don't have a CDROM (or your computer does not supportbooting from CDROM) and would like to simply install over the netusing PPP, SLIP or a dedicated connection, you should start theinstallation by building a set of FreeBSD boot floppies from thefiles floppies/boot.flp and floppies/kernX.flp using the instructions foundin Section 1.3. Restart your computer usingthe boot.flp disk; when prompted, insertthe other disks as required. Then, please go to Section 1.5.5 for additional tips on installing viaFTP or NFS.
