Solved Second HDD not recognised, can't enter BIOS

[Rustyy]

I have win7 premium home edition. I have added a second HDD Sata 1 TB. First time computer wouldn't boot. On restart it did boot, but windows explorer shows no second HDD?
Investigation says I probably have to enter BIOS to reconfigure somehow. However, I cannot get pc to let me enter bios.
I have a gigabyte card, and I think I have to press delete key, but continuously pressing key makes no difference. The pc still boots up as normal and still doesn't recognise new hdd.
Any help appreciated. Please be gentle, I'm an old codger.

OK, so I have managed to get into BIOS and new HDD is there. So I exited and while it didn't show up in Windows Explorer, as I hoped, it did show that it was looking for drivers etc, then asked me to reboot. I did this but 2nd HD still doesn't show in windows explorer. Device settings does show that it exists though.

Any ideas....anyone?????

Go to Windows Disk Management and see whether it needs to be assigned a drive letter. Also post a screenshot.

Yep, it has to be formatted and given a letter.

Post the shot of Disk Management, as asked.

You were correct, the drive did need formatting. Why didn't I realise this?. I don't know. Put it down to ageing.
Thanks all for the help.
