Daz Loader Windows 10
Maryetta Worm
A while back, I installed Windows 8 on my MacBook Air (mid 2013 model) using Bootcamp. It never really worked, (it would freeze all the time, the WiFi would cut in and out, etc.) so I got rid of it. I tried to do this through Bootcamp again, but for whatever reason this didn't work, so I booted up on a live Ubuntu USB and manually erased the NTFS partition for Windows.
Once back in OS X (Mavericks, but it was Mountain Lion when I installed Windows), I expended the default HFS+ partition to fill the full space of the SSD. So now I've got a nearly out-of-box Macintosh HD partition; everything on the Mac side works fine.
But lately, I find myself getting increasingly annoyed at the BSD coreutils among other things, and so I'd like to be able to dual boot into some version of Linux (probably Ubuntu or Xubuntu, but this is kind of arbitrary).
So but it turns out that when I "uninstalled" the Windows partition, something didn't quite update in the boot loader (I'm kind of fuzzy on my knowledge of the difference between a boot loader and a boot manager, so I might be using these terms incorrectly). When I start up my Mac holding down option, I get the following...
Now navigate to /Volumes/efi/EFI. This directory is supposed to only contain an APPLE directory. On a machine where I had Windows installed, it also contained a Microsoft and Boot directory. These can be safely removed, but for extra safety I would recommend renaming them to something different instead.
In the end, I gave up on actually removing the entries from wherever they're stored on the bootloader. Instead, I just installed rEFInd and manually removed the entries from the bootloader. I chose to go this route because after installing Xubuntu, this was the only way that my mac could find the xubuntu bootup file and also rEFInd has a feature where you can specify which entries you want to display and which you don't.
In Use Bootrec.exe in the Windows RE to troubleshoot startup issues (applies to Windows 7 and Windows Vista) they say to use Bootrec.exe with options /FixMbr /FixBoot, but when I type "bootrec.exe /FixMbr" in a command prompt, Windows says:
Alternatively you can use "Dual-boot Repair Tool" which has a graphical interface to bcdboot.exe, bootsect.exe and other useful functions like boot sector view and ... one click dual-boot repair function for Windows 10/8/7/Vista (also can fix Windows XP boot files).
The other answers given here work great on MBR/BIOS systems, however if you're on a UEFI system like I am, bootsect will just write a semi-functional boot MBR over the GPT protective MBR and bootrec just gives an "Access denied" error message, and neither one has a functional option to fix a broken EFI system partition, which on a UEFI/GPT drive is what contains the bootloader that used to be stored in the MBR. There's unfortunately almost no up-to-date guides on fixing the UEFI Windows Boot Manager (almost all of them just say to run the graphical Startup Repair utility, but that doesn't fix the problem in all cases), but I finally found the correct solution buried in this article, which requires the use of the bcdboot command instead:
Now do select volume x (where x is the volume number for the ESP) and then assign letter=N: to mount the partition. Run list volume again and note that the ESP is now assigned a driver letter. Run exit to leave diskpart.
(Optional) If you are not currently dual booting and want to fully clean the ESP before writing a new bootloader, run format N: /FS:FAT32 to reformat it as FAT32. This is probably not necessary under normal circumstances, however, as bcdboot seems to do a good job of cleaning things up itself. Especially do not do this if you have a Linux distro on another partition or else you'll have to reinstall GRUB as well once you're done with this. Also note that the following steps should not affect an EFI GRUB install as long as you do not otherwise delete GRUB's existing directory on the ESP.
Finally, write the new bootloader to the partition with bcdboot C:\windows /s N: /f UEFI. This command rebuilds a new UEFI-compatible bootloader on the ESP mounted at N: using the Windows installation mounted at C:\windows. Once it's done, you can verify the new bootloader was written by running dir N:\EFI, where you should see a Microsoft directory containing the new Windows Boot Manager as well as a boot directory containing the fallback bootloader (along with other directories for any other bootloaders you have installed, such as GRUB for Linux).
Symptom: Had a Windows 10 blue error screen directly after choosing Windows 10 in the grub boot menu with some cryptic error code, which shows not much information. It says I should press F8 for troubleshooting or Enter to retry, but F8 just shows the same error.
Notes:The problem other solutions tries have when you have a working grub you may not want to break that. As such, e.g. do not overwrite the MBR (breaks MBR and requires grub reinstall then) or overwrite the boot sector.
I know from past the major problem was when I removed Ubuntu, I either still got into the GRUB booting menu, or I couldn't boot at all, and had to format HDD and start over. Now I found an article practically saying the Windows loader should be back upon deleting Linux partition, so I want to make sure:
If I have Windows and Ubuntu dualboot, and I want to get back to Windows booting quickly itself without choosing from any booting menu, is it enough to just delete the Ubuntu partition? Will the Windows loader override GRUB?
This depends on whether your operating systems are installed in UEFI mode or Legacy mode.
(If your PC is manufactured in the last 5-6 years, and came pre-installed with an operating system, it will most likely be UEFI.)
There is a similar question that you can follow to check whether you are using Legacy or UEFI.
Note: Irrespective of which mode you install in, if you simply delete the Ubuntu partition, it won't make the Windows bootloader default automatically. You have to do it once, manually.
You'll most likely end up in a grub rescue prompt on the next boot. You'll need a bootable recovery disk (either Windows or Linux) to help you restore your Windows boot sector.
Here is a similar question that can help in this case.
You'll most likely end up in a GRUB command line prompt on the next boot, from where you'll have to boot to Windows and delete the GRUB EFI Firmware entry or change the order to put the Windows bootloader in the first place.
Here is a similar question that can help in this case.
Manually delete the GRUB EFI boot entry and/or set the Windows bootloader to the first position before you get rid of Ubuntu.
This answer to a similar question explains the process for deleting it in Windows.
Your DllMain function runs inside the loader lock, one of the few times the OS lets you run code while one of its internal locks is held. This means that you must be extra careful not to violate a lock hierarchy in your DllMain; otherwise, you are asking for a deadlock.
The loader lock is taken by any function that needs to access the list of DLLs loaded into the process. This includes functions like GetModuleHandle and GetModuleFileName. If your DllMain enters a critical section or waits on a synchronization object, and that critical section or synchronization object is owned by some code that is in turn waiting for the loader lock, you just created a deadlock:
Loader refers to the OS (module) loader.Loader Lock is a system lock used by the loader to synchronize calls to DllMain.This way, the loader ensures that initialization / cleanup tasks required by DLLs are performed in a thread-safe manner.
(...) the operating system has its own internal process-specific lock that sometimes is held while your code executes. This lock is acquired when DLLs are loaded into the process, and is therefore called the 'loader lock.' The DllMain function always executes under the loader lock; (...)
Few days ago I faced a big problem with my Corsair Raptor K40. The LED were almost all shutdown, it wasn't recognized anymore by the software and the most annoying thing : the LED for CAPS LOCK, NUM LOCK... kept flashing.
I saw in my Control Panel that the Keyboard was now recognized by Windows as a "KBD Boot Loader". So I tried to search for a solution on the whole internet, but nobody seemed to have the solution. I got even more worried when I came across this post from Corsair : Windows 10 Compatibility
I also read somewhere what upgrading to Windows 10 would cause such problem but actually, I managed to make my Keyboard works again. So this solution is certainly mostly dedicated for people owning this Keyboard and having upgraded to Windows 10.
I mahve this issue for a K30 Keyboard, I tried these steps and worked perfectly, but now i have an issue, the keyboard is detected as a K40, and all the keys are writing different stuff, i wonder if this is because of the K40 Firmware on my K30, I don't know if the K30 Firmware update exist, I can't Find it, does anyone have access to it?
my k30 woke up this morning the the same problem , there is no update and im buggered on how to fix it , one thing i can say i will not be buying there **** anymore , 1st my brand new headphones and now the poxy keyboard
Funny you should say that, cause I'm of the same opinion, since this is actually my second K30. First one just stopped working at all one day after maybe half a year of use for no reason, tech service didn't know what the problem was so they just gave me a new one. And now not two months have passed since that day and once again I'm having problems...
K30 and Vengeance K30 keyboards are being update since then with a software which I provided to you (Its the same 2013 software) and updates are being provided automatically from our server to your keyboard using this software.
This keyboard has a storage drive to with a maximum of 1mb to store firmware file and this what the keyboard uses to communicate to the software and computer, with this corrupted keyboard functionally will be gone as what you're experiencing.
