Re: [PLUG] Dual booting Linux and Windows

Bhaskar,

Rich said pretty much the same thing, that is my current working theory. I may try starting the install of Ubuntu 20.04 beta, just to see if it recognizes the drive. Otherwise I don't have a problem waiting for the full release.

Thanks,
Eric

It is quite possible that the Ubuntu kernel is too old for the new hardware you have. I have encountered that before, though I have not stayed current enough to hazard a guess as to what is not compatible. Try an Arch ISO with a new kernel and see whether that recognizes the drive.

Keith,

Running fdisk from the live OS shows only one device, the 3.8GB thumb drive. The 1 TB drive does not appear. It does appear in the BIOS, obviously since Windows boots to it.

Thanks,

It is possible, though not probable, that Ubuntu is not showing the drive because there is no free space on it.  That's never happened to me but I haven't dual booted with any Windows stuff in a long time.

When I do anything like that, I boot a "live" OS from USB so I can do all re-partitioning and resizing manually.

Have you checked to see if a live OS can see the SSD?  Since you turned off the secure boot items I can't see why you wouldn't be able to read and write to that disk.  Also, Rich M. did a presso on this awhile back and if I recall correctly, a trusted UEFI file would need to have a key.  You might want to enable secure boot again so you can turn that off (then turn off the secure boot again).

All,

Just got a new laptop. Don’t usually use Acer, but the Acer Aspire 5 came top rated for use with Linux. It also came with a 1TB SSD which makes it nice for dual boot, however I am having difficulty doing that. The existing OS is Windows 10 Pro.

I modified the BIOS to boot the thumb drive with Ubuntu Linux 18.04 LTS, and disabled secure boot. However running the Ubuntu install does not seem to see the hard drive and wants to install to the thumb drive, which it cannot since it is too small. Under the security tab there are other secure boot settings, but can only be accessed if secure boot is enabled. These settings include:

Secure boot mode: currently set to standard
Select an UEFI file as trusted

Note: A security password must be set to access the security and boot settings.

Anyone know the necessary settings to get Ubuntu to install for dual boot?

Thanks,
Eric
