You always need to be careful to install in same boot mode, or all installs in UEFI mode or all inBIOS mode. Windows requires gpt partitioning with UEFI and MBR(msdos) with BIOS. Ubuntu will let you use UEFI in MBR but really should not. You have one UEFI/gpt drive and two MBR drives. Grub can only boot other installs in same boot mode, so Ubuntu needs to be UEFI. converting sdb & sdc to gpt from MBR will erase drives so have good backups.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
