Grub see windows as sdb1 file system see it as sdb2

Started this new thread as the previous shambles was too convoluted. In the end decided to resinstall Ubunto 20.04 LTS never though to check windows disks. Windows previously sdb 1 and sdb2
The situation now is

windows in Grub sdb2 windows in file system sdb1

sudo blkid | grep UUID=

/dev/sdb1: LABEL="System Reserved" UUID="0AAA3702AA36EA39" TYPE="ntfs" PARTUUID="3767dd0a-01"

/dev/sdb2: UUID="EEF03A41F03A0FF7" TYPE="ntfs" PARTUUID="3767dd0a-02"

update Grub

Can this be fixed by Fstab, text edit,remounts or live windows or Ubuntu disks
If not should I reinstall windows or ubuntu which would be most effective and easy/fast to correct

Thank you
