I initially had Windows 10 in my laptop and decided to dual boot it with Ubuntu. I successfully installed Ubuntu 20.04, but now my laptop is automatically loading Ubuntu only. No GRUB menu is shown and no option for choosing Windows is given.
I did the same steps given in boot-repair site and it showed successful boot repair too, but nothing changed, still no GRUB menu.
What else can I try to fix this?
Often Ubuntu will not show GRUB by default, but you can learn how here: How to get to the GRUB menu at boot-time?
If you do not see Windows, try running sudo update-grub in the terminal, and the booting back into GRUB.
"boot repairs" are neither Microsoft or Ubuntu to be thought 100% effective or safe.
Consequently--(i)why not re-install both systems --if you have the discs?
Reason :-- Windows 10 should reinstall without any difficulty --
c/f 20.04 --is still not the official and tested safe release:
"Note that the recommended upgrade process currently displays the announcement of the development release, which is causing some confusion about whether 20.04 LTS is actually on-topic yet. – ændrük Apr 25 at 16:00 "
"Beware of the development release, my system had trouble to start after upgrade today. Cursor could move but system did not react to any action. Please also create an appropriate tag for Ubuntu 20.4 "– iArnold Apr 28 at 21:05 etc
hope not confusing.
