Hi there,
I purchased a new laptop (intel ultra 7 / 32gb ram / 1TB hard drive, came with windows 11). First time in my life I DIRECTLY installed ubuntu desktop 24. As part of initial installation Ubuntu took whole of my harddrive, i logged in with ubuntu password and used for exploring for few days. Hard powered off (long press on power button) while Ubuntu was running and after which I keep getting msg
Default Boot missing or boot failed
Insert recovery media and hit any key. Choose boot from usb.
Now when I put windows install usb drive and start windows 11 install from usb, installation says there is no hard drive (i guess since whole of 1TB is used by ubuntu).
Is there a way to completely format harddrive again and install windows 11? I anyway dont have any data since its a new laptop. Any step by step would be helpful to have windows 11 installed.

Thanks for your post.
It seems the hard drive cannot be recognized by your computer, so you see the error message that the bootable media is missing. Windows can still find the hard drive even if you have installed Ubuntu on it.
Please reboot your computer into BIOS/UEFI to see if your hard disk can be recognized. If not, ensure that your hard disk is properly connected to your computer. Try using a different SATA port or cable to see if that resolves the issue.
If the issue persists it might be a hardware problem, and you may need to contact the manufacturer for further assistance.
Best Regards,
