Just found out that my 3-year-old Intel NUC8 has got a new BIOS release 0090 recently. I downloaded and upgraded it without think twice (which is going to waste some of my time later.)
I have two OS installed and dual boot configured on the hard drive. Windows 10 alongside with Ubuntu Desktop. By default, it will boot into GRUB menu by default, where I can choose whether or not to boot into Windows.
I have done BIOS update for this NUC several times before. But this time, after the new BIOS update, the machine boot directly into Windows without showing the GRUB menu. I tried to hit F10 on-boot to bring up the Boot selection menu to choose another EFI boot-loader — but something weird is: There is only one “Windows Boot Manager” up there, the “ubuntu” boot entry is missing.

日了个特大号的狗了！ Holy super-sized shit! 刚才查看 fail2ban 日志的时候，被满满300多行日志吓尿 
。基本上从昨天中午开始就有个来自俄罗斯的 IP 一直在孜孜不倦地尝试进行 SSH 登录。通常被 ban 过几次之后攻击者就放弃了，哪会像这个家伙一样死心眼。而且我用的是非默认端口，这货应该是先扫描了端口
。 I was scared by fail2ban log of my server — more than 300 lines of log showing a same Russia IP address trying to SSH into my server since yesterday noon. Usually attacker will give up after got banned by fail2ban several times, but this guy is tireless. And the port I’m using is not the default SSH port, clearly this piece of shit did a port scan before attack.
