Win 7 and Mint dual boot problem

[Distorted]

After i start up my pc the grub screen pops up . now if i chose mint , it loads up no problem , but if i select windows , the windows boot selector pops up with options to load in Win or Mint ... This time if select windows , OS will load up fine but if you select Mint, boot error pops up and windows boot selector screen will reload again ... im not sure how all this came about but now i cant figure how to get rid of the win boot loader screen and let Grub deal with it like it did before this mess happened .

[trytip]

first thing to do is sudo update-grub

Yep - the Linux Boot Loader is pointing to the wrong Windows Loader,
& rather than to the Windows.Com program, itself.

so, what happens, after you have run sudo update-grub,
- is the Windows Loader - now correct ?.

sudo update-grub

Found Windows Recovery Environment on /dev/sda1

it's detected both the Recovery Partition & the Main Windows Partition:
- are you selecting that 2nd Windows System Loader ?
is that the Boot Loader that is giving that issue ?.

My thanks to administrollaattori and pierre !
I was browsing the forums and your posts pointed me towards the solution to a problem I had.
Grub (booting from Mint /dev/sdc1 ) was complaining that /dev/sda1 (Win10) 'was not a partition'.
I eventually discovered that /dev/sda was configured as a 'whole disk' (partition table = loop - i.e. no partition).
Once I made partition table = msdos (and restored the data & updated grub etc) everything worked as it should.
So thanks for giving me a nudge in the right direction,

okay so this what currently pops up in grub . yes the second option is what i select that takes me Windows Boot loader and from there i select win 7 again and loads up. The first option was something that somehow added in the options . i would like to remove that first option (Found Windows Recovery Environment on /dev/sda1) from list since it doesnt need to be on their

so, the Linux Boot Loader has detected that there is Two Windows Systems,
( two windows systems is quite common ) ( one is a Windows Recovery partition )
what I've sometimes done, is to re-label that Recovery Partition to "Don't Use",,
until such time, that do need to recover that windows system, that is.

it's the windows boot loader, that is giving you the issues & it's that Boot Menu that you need to modify.

okay so i need to boot into windows and modify mbr from there and if so how?

[trytip]

lsblk gives you what in Terminal?

ah No - not the MBR, but actually the Boot Menu:
this can be done with the BCDEDIT tool:

gives a description of how to use that.

okay i was able to modify my mbr in windows now i need to remove the windows recovery entry in grub as well . i selected the entry to see what would happen but all it does is gives me boot error so im gonna need to remove it

[Pierre]

what should happen, is that the windows recovery software should fire up

also - what I've done, is to keep that Menu Entry, but edit it's Menu Title,,
to read "Windows Recovery - - Don't Use This"
ie: you would only run this, for real - - to restore the Windows, Factory Configuration .. ..

OR - you can in your case , is to simply edit that whole entry, out of the Boot Menu itself.

windows 7 not appears in the list when I tap update grub.
Maybe I made a mistake, because I install win7 after mint. So now, can't choose dual boot only mint is on grub list when I boot.

Anyone helps me please?
Thanks and merry xmas

[Pierre]

so, when you have run sudo update-grub - - that didn't find the installed version of win-7 ?.

can you run the Disks program, & paste a screen_shot of that - back here ?.

[ilmago]

thanks for your reply. I am sending in attach a screenshot

[ilmago]

If I type following commands win7 starts

Grub> set root=(hd0,3)
Grub> chainloader +1
Grub> boot

I try also to modify the custom_40 file adding

menuentry 'Windows 7' {
set root=(hd0,3)
chainloader +1
boot
}

But still can't see win7 on grub menu
