sethu_payilagam: do you have linux?

we can show only linux in kanchilug meets

do you have any other spare laptop ?

or can you do a usb live boot ubuntu or linuxmint with your current laptop?

mohan43u: are u available

hariharan: yes

I have installed ubuntu in ssd using the 3 option without erase option in ubuntu installer

hariharan: great. did you have a seperate partition for home?

hariharan: what is your partition scheme?

I have updated the ubuntu after installing

Partition scheme means gpt or mbr?

hariharan: no. I mean how many partitions you have and how it was mapped, just run `fdisk -l | curl --data-binary @- paste.rs; echo` and send the link

I think i messed up with the grub bootloader part

hariharan: not booting?

hariharan: which ubuntu you installed? 24.04?

Before updating i have rebooted two times it booted properly

After updating the ubuntu it wont booting from the windows boot loader

hariharan: window boot loader?

20.04

Yes

hariharan: so you mean, you boot linux through window boot loader?

hariharan: not using grub?

Yes

Yes

hariharan: any specific reason?

I am having fear on partitioning and bootloader and bios setup

hariharan: ok, then how did you added the previous linux into windows boot loader?

Previous linux is configured with grub will switch device from the boot manager to the harddrive then ill access the ubuntu via grub

That not a straight way to touch nose but i used it

After ubuntu installation ubuntu shown directly on windows boot manager i thought that I'll able to boot with it. But after ubunutu update it showned its own face

hariharan: I'm confused now, as I understand, in previous OS, you kept 'windows boot manager' as the default bootloader, and 'ubuntu grub' was a second bootloader

hariharan: now something went wrong

hariharan: am I right?

Yes you are absolutely right

hariharan: what went wrong in the new install?

Forgot to complete the grub setup and disable windows boot manager

hariharan: you mean, new ubuntu install didn't setup grub? there is option to disable grub update in the ubuntu install step? or ubuntu failed to install/update grub?

I'll booted old linux and get you the partition scheme you asked

hariharan: no need. I understand you have home in seperate partition, that is enough

hariharan: in boot menu, do you see grub? or you only see 'window boot manager'?

In boot menu windows boot manager will show first

There i will choose advanced option to boot ubuntu there

hariharan: that means you see ubuntu in the boot menu, then you should be able to boot the new ubuntu, am I right?

Yes i thought like that but its not working

I expected ubuntu to boot when clicking

hariharan: what error you get when you select ubuntu from boot menu?

But blank screen only shown

Then i noticed no hard drive activity

hariharan: do you see the grub menu when you select ubuntu in boot menu?

No grub

Only blank

hariharan: no grub? can you just take a screenshot of your boot menu and share here?

Irc supports image sharing?

hariharan: no, upload it to your gdrive or somehwere, share the gdrive link

Okay i start a tlc thread that will be fine

hariharan: that will better

In the mean time i tried to add new os from my existing grub boot loader it started booting but endup with kernal panic
