Grub installed on the hard drive when installing Ubuntu on usb standalone

pl flag

I installed ubuntu for standalone onto a usb stick using usb to usb install, but it now seems grub is installed on one of my hard drives, I prev had a duel boot windows boot loader for 2 ver of windows which is still available, but I’m assuming grub shouldn’t be on my hard drive with a portable ubuntu install on usb stick, how can I safely remove grub from the hard drive ?

Very old bug in Ubiquity installer. https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1396379 You will need to add an ESP - efi system partition to flash drive. Use gparted to shrink any partition. External drives boot from same entry as an installer or /EFI/Boot/bootx64.efi or drive entry. If you want the "ubuntu" entry you can leave it on internal drive. Since you have install, you can copy ESP from internal drive to external, you can totally reinstall grub, but must change mount of ESP in fstab first to be flash drive's ESP not internal drive's ESP.

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.
