Ubuntu Clone/Resize Partition Fix

Once you clone the OS, the boot time will be very slow as the UUID for the partitions and the GRUB bootloader would have changed.

Trouble Booting into Windows from GRUB menu

• Run to show the efi boot orders: efibootmgr -v
• Check where the Windows EFI Boot file (bootmgfw.efi) is located, delete the 000X of Windows Boot Manger using efibootmgr
• Now create a new "Windows Boot Manger". (Refer this answer: https://askubuntu.com/questions/747215/edit-efi-file-paths-for-windows-boot-manager-from-xubuntu-14-04)

Boot time very slow

• Create a Bootable Ubuntu USB -> Try Ubuntu for free -> CMD -> Install boot-repair utility and run the recommended repair
• Now boot back into your Ubuntu and check if the UUID of swap in /etc/fstab matches that of the sudo blkid command
• Check /etc/default/grub and set "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noresume"

Now Reboot, that should fix the problems
