Replacing SSD - EFI and Grub arrangement - Windows + Ubuntu

br flag

Let me first explain my current disk arrangement status:

Disk 0 HDD - 1 tb - Ubuntu here

Disk 1 SSD - 128 gb - Windows + EFI partition

I'm using both systems on dual boot and it is working fine.

However, I will replace the Disk 1 SSD with other SSD of 256 gb. This SSD also has Windows installed on it. Let's call this new SSD "disk 2". It is currently partitioned like this:

Disk 2 SSD- 256 gb - Windows + EFI Partition..

My problem is: the EFI partition who has the GRUB that can recognize Ubuntu is on the Disk 1.

When I remove the Disk 1 (128 gb SSD), probably the other SSD (Disk 2 - 256 gb) won't be able to recognize my Ubuntu on the boot, probably only Windows.

How do I make this Disk 2 recognize Ubuntu? Do I have to install GRUB on the Disk 2 EFI partition?

Do I have to reinstall Ubuntu from scratch all over again?

Is there a way to make the SSD recognize my current Ubuntu?

I'm confused about what to do next.

Thank you!!!! =)

This is partly why I like to have ESP on every drive & have Ubuntu/grub UEFI boot files on Ubuntu drive. But all you have to do is reinstall grub. Total reinstall which will add the /EFI/ubuntu folder to new ESP and add new entry in UEFI boot menu. You can copy /EFI/ubuntu from old SSD to new SSD's ESP, but still need to use efibootmgr to create new UEFI boot entry. If new SSD is clone, the GUID/partUUID may be same & UEFI entry would work.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
