My Windows 7 is in the Legacy section of the boot order while an attempt at installing Ubuntu 18.04 put it under UEFI. To boot Windows, I have to disable Ubuntu. Enabling Ubuntu in the boot order boots only Ubuntu. There is no GRUB but I tried EasyBCD but it does not boot Ubuntu. A previous dual boot with a laptop running W8.1 was successful. There is supposed to be a confirmed GRUB bug with 18.04 but I'm not sure if this is the problem. PC is 64 bit. Due to a HD crash last year, there is no recovery partition but partitioning was successful.

UEFI and BIOS are not compatible. Once you start booting in one mode, you cannot switch. Or grub only boots other installs in same boot mode. You then can only boot from UEFI boot menu. Either reinstall Windows in UEFI boot mode or reinstall Ubuntu in BIOS boot mode. Micosoft has required vendors to install in UEFI boot mode since 2012, so most hardware is UEFI. And Windows 7 reaches EOL - End of Life in Jan 2020, so you need to start thinking about what Windows you want. microsoft.com/en-us/windowsforbusiness/end-of-windows-7-support or just stay with Ubuntu.

Thank you for the reply. What may have caused the problem is a repair center reinstalled W7 after a HD crash and HD replacement so the W7 is not an original install in UEFI. I do have a W10 ISO so that is an option but I would like to have Ubuntu as well.
