I partitioned my Vista drive and installed 16.04 on second partition and it was working fine. The small boot window at startup listed Vista to boot first and I wanted it to boot Ubuntu first. At some point I had a window offering me, what I thought was an option to boot Ubuntu first and I used the option and afterward I had no option to boot to Vista. I have tried a new grub menu tool and boot repair but they did not work. I am not at all familiar with how to use them. The "Disks" utility" shows just one partition. Is there any way to rescue the Vista? I have some important info on it

Thanks for the reply. fdisk info:

Also, my question is not the same as How do I recover my accidentally lost Windows partitions after installing Ubuntu?, because I partitioned my drive and installations were fine. My mistake was trying to change the boot order.

    It is unclear what you have done, but since Disks is showing just one partition, you may have deleted your Windows partition. Run sudo fdisk -l, copy the results from the terminal and edit your question adding the info. – To Do Jul 12 '20 at 07:04
  • My question was removed ? but it was not the same as a "duplicate". – user1104674 Jul 13 '20 at 21:49
  • I guess my question was removed because it was a duplicate? – user1104674 Jul 13 '20 at 21:52
  • My question was removed as a duplicate. But I lost my Vista part of my dual boot,which was working well when I tried to change boot order , I had the partition done correctly,Ubuntu offered me a way to boot ubuntu first and I may have lost athe windows partition, I'm not sure because you removed my question. Thanks – user1104674 Jul 13 '20 at 21:59
  • There's no Windows partition there. I suspect you reinstalled Ubuntu taking up all the disk and erasing everything else. It's probably late, but you could try testdisk to recover your lost partitions. It's quite technical. Look for a good tutorial before messing around with it. – To Do Jul 14 '20 at 21:13
  • @ToDo I'm not sure, but sdb1 seems like a windows partition – Dan Jul 16 '20 at 07:18
  • Thanks Eliah, I will try test disk, – user1104674 Jul 17 '20 at 01:47
  • Thanks Eliah, I did have the disk partitioned when I installed Ubuntu and it worked well for a few months . I lost the boot to Vista and probably it's partition when I used something in Ubuntu and it did not warn me that I would lose the partition. I think the devs should be aware of that , Thanks again for being the only one to help me. – user1104674 Jul 17 '20 at 01:57
  • For the devs to do remove any bugs, they would need to know what is this "something in Ubuntu" that caused the problem. You need to be more specific to receive attention. – To Do Jul 17 '20 at 06:51
  • Thanks ToDo and Eliah. – user1104674 Jul 23 '20 at 05:39
  • Thanks, I have not been able to run testdisk yet ,it appears to have been installed but # testdisk command only showed "sudo commands " list. – user1104674 Jul 23 '20 at 05:41
  • ran "sudo # testdisk and got this " mo@mo-HP-Pavilion-dv6000-GA448UA-ABA:~$ sudo # testdisk usage: sudo -h | -K | -k | -V usage: sudo -v [-AknS] [-g group] [-h host] [-p prompt] [-u user] usage: sudo -l [-AknS] [-g group] [-h host] [-p prompt] [-U user] [-u user] [command] usage: sudo [-AbEHknPS] [-r role] [-t type] [-C num] [-g group] [-h host] [-p prompt] [-u user] [VAR=value] [-i|-s] [] usage: sudo -e [-AknS] [-r role] [-t type] [-C num] [-g group] [-h host] [-p prompt] [-u user] file . – user1104674 Jul 23 '20 at 05:45
  • You're running it as sudo # testdisk, you should remove the # symbol. Use sudo testdisk instead. Also, [edit] your post instead of adding a comment. It's better because you can format the command output so we can properly read it. – Dan Jul 27 '20 at 11:17
