Nathan recently created a dual boot PC using Windows and Majaro Linux. But now his bandwidth speed on that PC is really slow compared to his other devices. Leo says that if the slowdown is evident on both Linux and Windows, then that points to a potential hardware issue. Leo recommends to boot into Windows and go into the Device Manager to make sure the PC is using the proper drivers. They should be by Intel. He can also do a Linux LSHW (list hardware) command, or LSPCI command which will show what ethernet and Internet commands are being used.
Hasan has been having issues using Citrix on his Windows machine. Leo says that Citrix works on Linux, so Linux is an option if you're sick of Windows problems. But if you want to use Windows, make sure you're running the latest version of Windows 10. But it will also clobber Linux if you want to keep that as well. So install Windows first, then install Linux for a dual boot system. Leo recommends Manjaro, but you'll have to disable secure boot on Windows.
Roger wants to know why his audio recording software will stop working if he upgrades to Windows 10. Leo says it may work if you use Windows 7 in Virtual Machine, where it's in emulation inside of Windows 10. Leo recommends VMWare. It will preserve your installation as a single file and then use it on any computer. The only limitation may be the hardware interface or dongle you have to use with the software. The other option is to go dual boot, where your PC will give you the option to boot into Windows 7 or Windows 10 when you turn it on.
Tom wanted to learn Linux, so he loaded up Linux on his PC. After a month, Windows now wants to install a feature update 1903 and now he's lost a partition. Leo says that Windows is being "bossy," thinking that it's the only OS you should have. So it "clobbers" your boot record and causes a boot-up issue. It's a common, yet complicated issue. You need to have a boot manager to sort it all out. Leo recommends GRUB. It gets loaded first and then asks you which OS you want to use. Most likely, the update redid the master boot record, damaging it.
Caller wants to dual boot into Windows with Boot Camp, but it's telling him that he doesn't have an Intel processor, so it won't work. He bought a used Mac, what gives? Leo says it may be that Mac doesn't have the most recent version of the OS (it's running El Capitan). Leo says to do a clean install of MACOS and do an immediately BootCamp installation. See if that works.
Rick upgraded Windows 10 on a secondary drive, keeping Windows 7 on his C drive. Now he has a dual boot option. However, with Windows 7 support going away, how can he make sure he's OK if he has to replace that secondary drive? Leo says it'll authenticate automatically because Microsoft gives an entitlement based on the entire machine, not a hard drive. If he had to replace the motherboard, video card and hard drive, then he'd have an issue. But changing a hard drive won't cause the problems.
Ray wants to know if you can dual boot a Windows machine with Apple OS X. Leo says no. You can go the other way around and boot up to Windows 10 using boot camp, but you can't make a Windows machine run OS X unless you do a "hackintosh" setup, which is a direct violation of Apple's terms of service. Plus, Apple won't sell you a copy of OS X without a computer.
Charles would like to create a dual boot system on his laptop with Windows and Ubuntu Linux. How can he do that? Leo says that running Linux on his computer is a great journey and it has become a lot easier to create a dual boot system with Ubuntu. All he needs to do is download the installer to a USB key and then boot to it. Then it will walk him through creating the dual boot portion. Then when he boots up every day, the GRUB boot manager will ask him which OS he wants to load.
Bruce does both Mac and PC work, and he's looking for a laptop that can handle both well. Should he buy a PC centric computer that can run a Mac virtually? Or the other way around? Leo says that there is no way to run macOS on anything but a Mac, especially not virtually. He could do a hackintosh, but not on a laptop. So Leo says go the other way, and get a MacBook Pro running Windows in Boot Camp.
John has an old PC that runs XP and he's going to install Debian Linux on it. He wants to keep XP on it to run dual boot, though. Can he still get Service Pack 3 to get it up to date? Leo says that Microsoft has killed XP development, so he can't really get ahold of it except through a third party archival service. He'll have to decide if that's legit. If he installs Linux first, it may prevent installing Windows XP in the process.
