@sharicov I noticed you had a couple of other items in your solution that could possibly be solved with this idea (iso boot and recovery partition creation). If you are still concerned about those issues, you should submit them as 2 separate ideas since they both probably have other solutions to solve them (like the extra kernel removal solution cheesehead pointed out).

This kind of question pops up regularly in the forums from users who are moving from beginner to intermediate users.
There are already easy ways to manage kernels, to choose default grub entries, and to boot from a live-reinstall partition. The users in the forums just generally don't know about them (synaptic, update-grub, set-grub-default, unetbootin, etc.) yet.
Is there room to create a single GUI for all this?
Sure there is. Most of the desired functionality is already available through dbus, so all (I think) it really needs are a couple community members willing to learn dbus, build the GUI, package the new control panel, and submit it to Ubuntu.
Approving for 30 days to gauge community interest.
Great idea, a good GRUB GUI, that allows as Multisystem with USB does easily add ISO to boot.
With a /boot partition when you need to format and install a new version - sometimes better tahn upgrading - no need to use a CD/DVD or USB.
Add the new version iso to grub / burg reboot and install from ISO, also good for have 2 installations, for instance one with Ubuntu Studio low latency kernel an xubuntu and other with Ubuntu Unity for different tasks.
Or even to have rescue distros as trinity rescue or others at the /boot partition.
I posted a similar idea some time ago and was rejected inmediately, better luck this time, but I also posted an idea for a Ubuntu isntaller for Android rejected, and there are already such tools at Gplay and even Ubuntu has an Ubuntu for Android version.
