I have an Acer Aspire 7730 laptop (Acer Aspire 7730). After a power failure it shows me only the GNU GRUB menu with these options:
- Ubuntu, with Linux 220.127.116.11 - generic
- Ubuntu, with Linux 18.104.22.168 - generic (safe mode)
- Memory test (memtest86+)
- Memory test (memtest86+, serial console 115200)
If I choose either of the the first options it starts the busybox menu. Can I fix this from this console or must I use a live CD (which at the moment I don't have)?
