After install 18.3 can't boot Win10

Post by Duke49th »

Not urgent problem which is why I ask only now. But it bothers me as I still use the one or another program in Windows...well...I want to lol.

I installed it that way:

C: SSD with 2+ partitions. One for Windows 10 and later on installed 18.3 core/swap on that SSD in a separate partition. Home went into another harddrives partition.

I followed a tutorial where on the screenshots it looks like it suggests that I use Windows Boot partition for the bootmanager. You know, the dropdown option below the partition window "Device for boot loader installation"

Everything works fine. But. When I chose Windows 10 from bootloader (GRUB?) it just went black for a second and brings me back into the bootloader. No error messages etc.

Any ideas?

Btw boot is from BIOS/Legacy, not UEFI.

Thank you.

For Legacy BIOS dual-boot install, the "Device for boot loader installation" should be the internal hard-drive or /sda, ie not the Windows Boot Manager or Partition = you likely need to repair Windows Boot Manager and reinstall Grub at the same time = quite complicated. Hopefully, someone more experienced will come along and help you.

If I were in your position, I would reinstall both OS, ie Windows, then LM, after backing up my data.

Oh crap.

It's Win 10, I have no DVD Rom. Maybe I can do it from an USB Stick. I got the Key from early beta release back that time inlcuding a microsoft account. But even if I would have a DVD, I have no DVD Rom on my desktop. :(

Thanks for the heads up. Then I don't know why tutorials don't show correct screenshots. This was clearly missleading then. :(

On my laptop I let Mint just install it automatically beside Win 7. But on the desktop I've chosen "something else" and followed the tutorial to not mess up something. Well...didn't work out.

With Legacy BIOS, it is a mistake to install grub into Windows partition. The next command tells where grub is installed.

Code: Select all

sudo fdisk -l 2>/dev/null | egrep "Disk /|/dev/" | sed "s#^/dev/#Part /dev/#" | awk '{print $2}' | sed 's/://' | xargs -n1 -iX sudo sh -c "dd if=X count=1 2>/dev/null | grep GRUB > /dev/null && echo Grub found: X || echo no Grub: X"
If Grub is installed into Windows partition, you need to fix Windows boot using Windows DVD using command

Code: Select all

bootrec /fixboot
DO NOT run

Code: Select all

bootrec /fixmbr

HI. Thanks. As bootrec /fixboot gives me an acces denied (I have BIOS boot, not EFI..maybe thats why) I guess I have to fix it the hard way and fix grub afterwards.

I'll report back later.

Windows 10 can be installed from a flash drive, it was how I did it back in the day. IIRC M$ has free utility to create a bootable Windows stick. My process would be to install Windows first, let it "customize" itself into updatedness (probably take you a couple of days for that :(). Once it is stable and working, installing Mint from a live stick which should take about 20minutes including all updates!

Maybe, you just need to "Run as Administrator". ... https://www.digitalcitizen.life/how-run ... -windows-7

When I want to make a bootable Win 10 USB Stick in Mint, I found out that I already have one :D I just forgot that. I hope I don't need to install it again. I wouldn't do that at the moment. I am lucky and have fast internet and a SSD, but still this isn't what I want.

@Michael Louwe: As I use the console from the Win Setup, I can't run anything as Admin. But it's ok. I am at work now but later I'll just try it the other way described in the link above.
