Windows 10: Making a ChromeOS partition bootable on a Windows Laptop

down votefavorite

I have a Lenovo Yoga 3 Pro I want to use ChromeOS on, in addition to Windows 10. UEFI is enabled in the BIOS.
I have successfully installed ChromeOS (CloudReady) and then used it once. But I can't boot to it to get back to it. It seems the process didn't make the disk bootable.
In Windows Disk Manager the Partition is set as a Primary Partition but isn't set as a Boot disk. And there is no option to.
In the command line diskpart I cannot make it Active. I get the error:
The selected is not a fixed MBR disk. The ACTIVE command can only be used on fixed MBR disks.
When I select the inbuilt Lenovo boot manager I get a choice of the SATA HDD or Windows Boot Manager. Both arrive at the same place - Windows.
How do I make the partition bootable?

Making another HDD partition bootable

The issue is as following:

I have a first HDD with its first partition set as bootable, having boot manager that includes options to load WinXP (this HDD) and Win7 (on another HDD).
I will be replacing the first drive with a new one - so what's the trick to make Win7 HDD bootable and boot Win7 without the need to reinstall anything (way too much hassle)?

 

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

 

Multi-bootable USB

Hey guys from TPU, couldn't find any specific thread pertaining to the question asked on title. As mentioned, I'm trying to create a bootable USB, but with many specifics boots available.

I've been trying to create one with multiple boot device including one that enables me to run Windows 10 directly on the USB Thumb Drive but to no avail.

The list of bootable images i'm trying to create are

1. Windows 10 (A full OS running from thumb drive)
2. Windows 10 ISO (Bootable disk image for fresh install)
3. MemTest86+

Have tried YUMI or UUI from the website USB PenDrive Linux but as this is my first time, i don't know how am i screwing up or am doing it right.. Anyone got a rough idea on a step by step guide? Thanks!
