Dualboot problems (Dude, where is my windows!?)

I know this is being asked over and over and over, yet I must say that I have been using all the free time I got since 48 hours ago to solve this, I checked out endless answers, and I just dont know what to do anymore...
lets see:

-There is Windows 7 'W7' and Windows 10 'W10' in (hd0).
-W10 makes me gag so i decide to install BL there instead.
-Install bunsen labs. Obviously doing something ridiculously wrong even though i ve done this a gazzilion time years ago.
-Grub only shows bunsenlabs.
-2 days of reinstalling, online investigation enless console writting and a mild nervous breakdown laterthis is how my partitions look:


https://preview.ibb.co/g3v2HG/Screensho … _30_PM.png


NFTS "W7" is the partition where windows is at, I can mount it an see and acces the files
here are the details of W7:

both of those unalocated parts i dont know why are there...

this is what happens when I run grub-update:


https://image.ibb.co/gQ64hG/Screenshot_ … _23_PM.png


grub-probe error just appeared today, have no idea anymore...
i have grub-install and reinstalled...
what else....

I tried to add the entry manually with /etc/grub.d/40_custom:

I made several different entries to see if any of the different possibilities might work:

https://preview.ibb.co/feP4Gb/40_custom.png

all of them leading to the bautifull:

https://image.ibb.co/dhJ9hG/image15.png


so, all I want is windows to appear in grub, like it should (or im used to) and just load so I casn work with my music etc.
Thanks a million in advance for your time and lets see if any of you can help me out with this, I honestly  never been so stuck with this...
ill be here untill it gets fixed so ill be able to reply soon.

Re: Dualboot problems (Dude, where is my windows!?)

-2 days of reinstalling,

Did you try re-installing Win 7 as well?

From your gparted shot, it looks like you deleted the partition Windows 7 (8,10) used to store it's boot files.

sda1, sda2 in this scrot:

scrot-shot-January_-5_1515183462.th.png

Pretty sure you'll need to do a clean install of Windows 7 to fix that.

For a dual boot on a single drive, clean install of WIndows 7 first then BL.

Never tried; after you create the partition, you would somehow have to get the Windows 7 boot files onto it - need the Win7 DVD for that - and register it with the installed W7.

Re: Dualboot problems (Dude, where is my windows!?)

Doom666, on their website they tell to use unetbootin: https://sourceforge.net/p/boot-repair-cd/home/Home/
Maybe try that, as some live discs don't have proper bootloaders.

should be /dev/sdb i.e without the 1 on the end. You dd to the device, not a partition on the device

I think that at this point you removed a partition that Win7 needed to boot.

I've moved this thread to Help & Support (Other) as it is a Windows-related problem.

Re: Dualboot problems (Dude, where is my windows!?)

If you can mount the partition and see the contents, then we know it is there. It just becomes a matter of finding it. Your grub bootloader has to be on /dev/sda1. Additionally, ensure that os-prober is installed. The last thing is, are you on a UEFI bios? Your Windows install appeared to be a legacy install to me.

all the data is there but people say that a very small partition should be there in order to boot it, i erased that partition somehow.

Your grub bootloader has to be on /dev/sda1.

I believe it to be installed on /dev/sda so lets see:

first i install it in sda:

odemark@Deuterium:~$ sudo grub-install /dev/sda
[sudo] password for odemark: 
Installing for i386-pc platform.
Installation finished. No error reported.

then install it in sda1:

odemark@Deuterium:~$ sudo grub-install /dev/sda1
Installing for i386-pc platform.
grub-install: warning: File system `ext2' doesn't support embedding.
grub-install: warning: Embedding is not possible.  GRUB can only be installed in this setup by using blocklists.  However, blocklists are UNRELIABLE and their use is discouraged..
grub-install: error: will not proceed with blocklists.

scary enough... i dont know what that means

Additionally, ensure that os-prober is installed.

How?




The last thing is, are you on a UEFI bios? Your Windows install appeared to be a legacy install to me.

i dont think i install it UEFI (whatever that means) i chose the other version, but anywhay, how can i find out?

I seem to remember doing something very similar to my old Win7 system and the repair disk told me that a re-install was needed.

Do you have the original disks?

You can download a (3 month) "trial" version from Microsoft and activate it if you still have the code (I think).

Having said that, it has been _many_ years since I've run Windows full-time so I'm probably not the best person to ask hmm

i managed to make a live usb now but i noted that only boots on UEFI mode and dosent solve the problems with the automated one click fix. now, there is one option that says something like restore boot partition, but also asks to make a backup first, now how can i make a back up of W7 to an external hard drive i have?

It means that GRUB will not proceed unless you force it (don't do that).

apt-cache policy os-prober

It should already be installed though; it's not doing anything because there is no Windows bootloader on your disk (IMO).

hehe, bought the computer  from second hand, where do i find that code? I can acces all windows files


its possible to dd the WHOLE W7 partition so i can install whatever ffree w7 and then back up everything?
is so, how?

My refurbished X201 has the code on a label on the underside, I've never tried using it though big_smile

Re: Dualboot problems (Dude, where is my windows!?)

Download the trial then use the code to activate Windows.
Here are the steps to take:

  1. Decide if you want to run in Compatibility mode or UEFI. This is important because if you run using UEFI, Linux and Windows both will need a GPT partition scheme. If you go with compatibility mode, there is a chance Windows 7 will refuse to boot. <-- I am not sure about this because I never ran Windows 7. However, Windows 10 requires a GPT partition scheme. My guess is that UEFI was enabled on the device because you somehow lost the Windows boot partition.

  2. Since you can mount Windows and see it, copy everything important to you off of that partition and stash it someplace safe.

  3. Install Windows.

  4. Activate Windows.

  5. Install Bunsenlabs.

  6. Install grub onto /dev/sda when it asks

Windows always has to be installed first because it will overwrite grub.
The corollary to that is that Grub has to be on your Windows partition in order to see Windows, I think. Feel free to correct me if I am wrong but I always put the bootloader onto the drive that Windows sits on.

The key here is that you somehow overwrote your windows boot partition. If you are lucky, sometimes you can do like a system restore with Windows tools, assuming you have not overwritten the partition with the install media.

Re: Dualboot problems (Dude, where is my windows!?)

Decide if you want to run in Compatibility mode or UEFI.

how can I decide that? what are the differences? what does it even mean? all I know is that when setting the boot order , it shows either USB Bunsenlabs and then is another option UEFI Bunsenlabs, that is all i know about this, and is also the first time Ive seen this, several years ago when I did this last time, i never saw any UEFI thing... -__-
what would you recomend  ?

It is a recently-added option wink

The entry chosen will dictate the type of system installed but note that GRUB (the bootloader) will fail to install to a non-UEFI system with a cryptic error if a GUID partition table is used on the disk but a BIOS boot partition is not created beforehand.

Also, Windows will only install a UEFI system to a disk with a GUID partition table.

If the disk has an ms-dos ("MBR" type) partition table then Windows will install a non-UEFI system.

Re: Dualboot problems (Dude, where is my windows!?)

^ ¯\_(ツ)_/¯

If nobody else here can answer your questions then perhaps try a Windows forum?
