TinyCore does not boot after installation

[jazzbiker]

You can look what's happening with Your eMMC disk.

1. Boot from the USB drive.
2. Run terminal or boot to base (CorePlus boot menu option).
3. run

Code: [Select]

fdisk -l

Check, whether eMMC has bootable partition.

This may be UEFI dirty tricks. Your machine had Win preinstalled. Now You'vw destroyed this installation, but UEFI still remember it. In Your BIOS screen You see some options about "DELETE ..." Maybe it is option for editing the UEFI table. maybe You will enter this option and will see Win there. In such case You will need to delete it from UEFI table, because the installation is absent.

It seems that if I'm not mistaken there is an asterisk on the partition I tried to install (mmcblk0p1)

I don't see anything there unfortunately

And if You enter [Select one to delete] what do You see?

[jazzbiker]

Another mystery for me are mmcblk0boot0 and mmcblk0boot1 partitions. Can PiCore masters educate us a little, what are these artifacts?

Nothing

I also wondered to myself, I have no idea what that means

Hi newbieCore
I don't see your hard drive listed under  Boot Option Priorities.
If you go to  Hard Drive BBS Priorities , does it show up there?

No, nothing appears there either except the usb

[jazzbiker]

I suspect mmcblk0boot0 and boot1 to be physically separated from eMMC. Maybe they are ROMs included into the address space of mmcblk0. I think so because tc-install is zeroing partition table, and these two 4M pieces must not exist.

Edit. Wait, they are really separate drives, sorry.

I'd propose to load and install efibootmgr.tcz and read the boot stuff with its help.

@newbieCore, You can install TinyCore to another USB flash drive and boot and work with it.

It’s say
EFI variables are not supported on this system.

Hi newbieCore. I get the same message on my X230 laptop which is working perfectly with Tiny Core Linux:

Code: [Select]

$ efibootmgr
EFI variables are not supported on this system.That just means that your system, like mine, uses legacy BIOS and not (U)EFI. More details here.

Hi CentralWare!

If he is able to boot from the USB, doesn't it mean that Secre Boot is already disabled?

That's right, I already disabled it

@newbieCore, If Your box is not twisted with UEFI, then what did You mean saying that You've already disabled Secure Boot? Just curious.
