Grub dual boot: Mint update removed grubentry for windows

view full story

http://superuser.com – I have a problem where Mint updated my system,and also changed my grub2 entries. It needed to do this.. but in changing grub entries it REMOVED my Windows on /dev/sda1 entry. I can still see the partition being present if I check with "disks" tool from the menu but I cannot get the vital information of the UUID. Now I cannot even attempt to add a new windows entry in grub. Any tips? I tried blkid, which does not give me sda1 info. I tried vol_id but not present on mint I figure that as soon as I have the UUID, at least I can attempt a restoration. (HowTos)
