I have recently tried to update my Elementary OS from luna to freya but somehow it failed so I uninstalled the OS but somehow traces of grub is still on my computer preventing me from booting into my windows 10. Now that whenever I start my computer i receieve the message: ' error: unknown filesystem. grub rescue>_ ' I tried loading the windows 10 disk from a bootable usb stick and fixed the mbr in command prompt but i still end up looking at the same message. I pretty much tried everything (turning off uefi in bios, chaning boot priorities..) somehow i just can't get rid of grub even after uninstalling the OS. i really need some help, maybe i messed up my partition table? or maybe there's something wrong with the bios bootloader that keeps trying to load grub?

I'm unsure why sda5 became vista(i installed elementary os on this partition but then uninstalled) I've already ran bootrec /fixmbr and fixboot and both returned succesfull in cmd (windows 10 bootable disk) but the default mbr is still grub, how can i remove it. Can someone look at my partition table and check if the bootflag is correct or wrong? How can i rejoin the sda5 with sda3(D drive)

Solution: - load up gparted and change the boot flag to the one which says OS (sda2 in my case) - use the Boot Repair tool - reboot :D
