ph flag

I have a working dual boot option on my pc with Windows 10 and Ubuntu.

I have installed a new SSD on this PC and installed a new version of Windows on that new SSD. When I boot from this new SSD, I can see the new Windows running.

I would like to have a boot option to have 3 options

Can I modify/reconfigure the grub to have 3 boot options in ubuntu to have following options

1.ubuntu 2.Windows 10 3.Windows 10 new version on the new SSD drive

Thanks for your assistance

Are all installs in UEFI boot mode? Does each Windows has a separate ESP - efi system partition? If so then grub will automatically find two Windows installs. But if when you installed Windows, it saw first install, then it overwrote its /EFI/Microsoft folder & updated BCD to dual boot from one BCS. https://askubuntu.com/questions/653101/boot-repair-windows-not-listed & https://ubuntuforums.org/showthread.php?t=2478842

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.
