Dual Boot GNU GRUB 2.02 change?

Can I remove the 2nd Windows 7 boot and how do I do this.

Thanks for any help

Rich.b

Do you have Windows on sda and sdc?

on a ssd sda
was the first to be installed

Is the system branded? Does it have a recovery partition?

Home built PC not branded. Window 7 Pro has a backup but not sure ware this is stored. Ubuntu I have copy of my file on a separate portable 2TB HD. Also I did an Windows backup to this same 2TB using Paragon programme.

I hope this information is what you are looking for - Thank you for your help.

Richard.

Details of my PC and it has Windows 7 Pro Dual Boot Ubuntu 15.10 installed.
PC Spec:-
ATX case with 500Watt PSU
Gigabyte Socket 1150 Micro ATX Motherboard - GA-H81M-S2H
Intel Pentium G3220 3.0GHz - BX80646G3220
8GB DDR3 1600MHz DIMM - PC3-12800
128GB SATA-III Solid State Drive - Kingston V300
500GB HDD Seagate Barracuda SATA3 - ST500DM002
Internal SATA Multi-format DVD Writer – SH2-244DB
Multi Card Reader – CR005V4
Windows 7 Professional – 64 Bit
Installation Type:-

/dev/sda3 ext4 49.67Gib 5.93Gib 43.Gib
/dev/sda4 extened 12.36Gib
   /devsda5 linux-swap

/dev/sdb format - Size - Used - Unused - Flags

unallocated 1.02Mib

Your output is somewhat inconsistent.
The original question talks about sda1 and sdc1, but now I see sda and sdb disks.

In any case, in your last output the partition /dev/sdb1 is listed as bootable with ntfs formatting. This might be some kind of Windows Boot loader, that is interpreted as "Windows 7" by grub, but can also be something else that is wrongly categorized by grub.

Running the boot-info-script would most probably show more details about that partition.

Ran boot info script, but unable to locate "Results.txt"

It defiantly said

Windows 7 (loader) on /dev/sda1

Windows 7 (loader) on /dev/sdc1 (and does say sdc1 in Grub)

Any advice please.

Note that ext HD 2TB was connected when above file was recorded.

I think that I see the cause of your problem.

I assume that sdc is the external 2TB disk that you use for backup.

Part of the output

Device UUID TYPE LABEL
/dev/sda1 8AE611C9E611B683 ntfs System Reserved
/dev/sda2 8AA62C62A62C50CD ntfs
/dev/sda3 70ac6c90-ccf1-4e57-8d4f-beafbdd23b0d ext4
/dev/sda5 638fed9b-133f-4943-ad7f-ecc52e2584d6 swap
/dev/sdb1 749875FB9875BBE4 ntfs New Volume
/dev/sdb2 10ed14f1-ae80-4017-849e-e94c2e510081 ext4
/dev/sdc1 8AE611C9E611B683 ntfs System Reserved
/dev/sdc2 8AA62C62A62C50CD ntfs
/dev/sdc3 3726180A54D4BBA9 ntfs

shows that sda1 and sca1 as well as sda2 and sda3 have identical UUIDs. This is not good, because you cannot predict which device a program will access when using the UUID.

In your case this most probably was caused by cloning the Windows partitions during the backup creation.

The solution for your problem (double occurrence of Windows in Grub menu) probably is the following:
Perform a safe remove (eject) of the external disk
run the command

sudo update-grub

Thank you Manfred -

Second entry of " Windows 7 (loader) on /dev/sdc1 "

Now gone.

Thanks again

Thanks Manfred Hampl, that solved my question.
