I recently bought a Lenovo Y580 with an SSD acting as a cache for the main drive. This seems to cause some issues when trying to dual-boot Windows and Fedora, since the SSD is the main drive (sda) but the Fedora installer considers this drive to be unformatted and seems to skip the bootloader options screen when I tell it not to use the SSD. So, when I get to partitioning the storage drive for the install, the installer complains that I haven't set up a bootloader.
So, just to clarify:
1. I open the 'Install to Hard Drive' shortcut
2. I select a keyboard language and click 'Next'
3. I select 'Basic Storage Devices' and click 'Next'
4. The installer asks if I want to remove the SSD from the installation - I click 'No, keep any data'
5. The next screen I get asks me to select a hostname
6. Timezone selection
7. Password selection
8. 'Use free space' (I've shrunk my Windows partition by 200GB)
9. Error: you have not created a bootloader stage1 target device, sdb6 must have one of the following disklabel types: gpt. I also get this error if I try and set up a custom layout.
Is there any way to either get Fedora to install the bootloader to sdb (which will be chain-loaded from the Windows bootloader) with this setup (or otherwise fix this issue)?
