Using Windows 10 and Linux on the same auto is atrocious . At multiplication , the UEFI inviolable thrill break GRUB and the other times GRUB can not just reboot Windows 10 . Recently , I upgraded Ubuntu to 19.10 Beta from Ubuntu 19.04 . Now , Ubuntu 19.10 derive with the new version ofGRUB 2.04 which reportedly has set of hemipteron . In my shell , GRUB somehow mess up Windows MBR location and now I can not boot to Windows 10 . To fix things , I extend a couple of whole step and here is a elaborated guide on how to fix Windows 10 not booting up on Linux .
Fix Windows 10 Not Booting up on Linux
If you are on Ubuntu 19.10 Beta , the GRUB 2.04 has a quite a little of glitch . It would be better to downgrade to Ubuntu 19.04 or move entirely onto Windows . skim tothis stepto check methods to vary the default bootloader to Windows NT .
1. Rebuild GRUB
At times , GRUB has problems locating the Windows MBR file on your disks . The first step would be to verify if Windows 10 can be observe by Linux . To do that , start the undermentioned dictation .
The above bid will look for other operating organisation installed on your disks . If Windows is detected , you would get an output like below .
If the above command is capable to find the Windows 10 operating system , then we can rebuild the GRUB form file . To do that , use the undermentioned command .
The above command initiate glance over of all the partitioning on your local disk and looks for various Operating system install . If it detect Windows 10 , you should get a similar output as below . The command will mechanically create a Windows ingress in the configuration Indian file as well .
2. Boot Repair
If the command line is not your cupful of tea , you’re able to alternatively try the graphic Boot Repair tool . At times , the GRUB file is broken . The Boot Repair tool automatically seek for other operating system on your disk . It also repairs and rebuild the GRUB constellation data file . It is like to manually running os - prober and rebuilding the GRUB conformation file .
To commence with , use the following commands to add the expect repository and put in Boot Repair .
Next , launch the thrill repair tool . It will take a minute or two to scan all your disks and partition . Once done , snap on “ Recommended Repair ” . This option will blue-pencil the old GRUB filing cabinet and reconstruct it from scratch .
The next screen will present to you a set of commands which you have to copy and paste in the terminus . Just follow the on - cover instructions provided by the Boot Repair tool and it will repair the GRUB single file for you .
Boot Repair will give you an unexpected error if you are using a beta reading of Linux distro .
If this method does n’t ferment for you , chances are the Windows Boot manager file can not be detected by GRUB . Hence , we would need to make an entry for it in the GRUB form single file .
3. Use GRUB customizer tool
directly up , I would n’t recommend manually updating anything in the GRUB conformation data file . We will habituate an open - source tool called Grub Customizer . launch the following commands to download and instal the cock .
Next , we require the location for the boot dock-walloper of Windows 10 . To find out that , go the stick with command in the end .
Check out for the partition which has setting degree as “ /boot / efi ” . This is the segmentation where the Windows boot director is installed . We necessitate the twist name of the particular partition . In my case , it is sda1 hence the charge single file location is “ /dev / sda1 ” .
or else , you may also install dwarf - disk - public utility which is a graphic cock to expose the disks and partitions . On the menu , you’re able to look for the EFI System partition . The division description should seem something as watch .
Next , lead over to the GRUB customizer tool and tick on the page icon at the top to make an introduction .
On the entry editor pop - up , select the character as “ Chainloader ” and partition as “ /dev / sda1 ” . you’re able to also provide a desirable name to the entry . Post this , shoot Enter .
You would now be able to see the introduction you have create on the Grub customizer menu . However , you need to penetrate on Save to synchronize the changes with the original GRUB configuration file .
Finally , do a restart and now you should be able to reboot to Windows 10 . In fount you ca n’t , most belike the Windows MBR is broker or thrill files have gone corrupt .
4. Startup repair
If chow can not load Windows MBR , chances are the file may be corrupt . We can rectify it using a Windows ISO file and a flash drive . you could use anyUSB bootable software system for Linux . I would recommendWoeUSBas it is simple and set out the job done apace . Once you have the USB drive ready , boot from it . Click Next on the first screen and then press “ bushel your reckoner ” on the next screen .
On the next page , get across on Troubleshoot choice and finally get through on “ Startup Repair ” . It would take a while to pay back the boot files and MBR .
Most of the time , startup fixture will fix the Windows Boot single file . Once successful , reboot your automobile and GRUB should be able to reboot up Windows . If still there is a job , we would need to swop the bootloader back to Windows NT .
5. Change default bootloader
If you are trusted that the Windows startup file is not corrupt and you have n’t mistakenly wiped off C Drive , we can convert the bootloader back to Windows NT . To do that , boot from the Windows USB , select Next on the first silver screen . Next , select Repair your computer and then on Troubleshoot .
On the advance options page , select “ Command Prompt ” .
On the dictation pedigree , melt down the following dictation .
The above - bring up instruction will change the bootloader from GRUB to Windows NT . Now , when you reboot your system , it should boot straight to Windows . In case you are coming from Ubuntu 19.10 , you would need to roll back to Ubuntu stable 19.04 as GRUB 2.04 has scads of hemipteran .
6. Fresh Install Windows 10
In case none of the above method acting forge for you , chance are you might have accidentally wiped off Windows . The last resort is to do a unfermented install of Windows 10 . The secure matter is you would only require to format the coulomb drive and information in other drives wo n’t be lose . But still , you would end up mislay single file on the screen background , Downloads , and Documents folder .
