Did both of the operating systems appear under Default operating system, and is "Time to display list of operating systems" checked? Let me know. How satisfied are you with this reply? Thanks for your feedback, it helps us improve the site. Hi Papalyons. Were these managed by a Windows boot menu created during install or were you booting them separately by choosing the hard drive from the BIOS Boot menu at startup?
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved. The pages appear to be providing accurate, safe information. Am I missing something here? Yes, the device for boot loader should have been sdb instead of sdb1. You can then make sdb the default boot device, so you get to choose between Windows or Ubuntu whenever you reboot.
I did what you said, but the problem persists. Algorithm is a 3-day conference on blockchain, cryptocurrencies and AI set for Feb. Partner links. Attend Algorithm Conference Reasons to use control panel for your server. Dual-boot Ubuntu July 23, Pages: Page 1 , Page 2. Share on facebook Facebook.

To the 2nd question, the answer is a yes. Thanks in advance! Reply to John 8 years ago. If I dual boot install both Ubuntu and Windows, is it safer to install them on two different hard drives than different partitions on the same hard drive?
What risks may be involved? For example, one OS does not recognize the files of another OS. One OS accidentally wipes out the other OS by some system operations? In general, they should leave each other alone. If you do the install correctly Windows first, then Linux, as a rule, because Linux is more 'considerate'.
As far as I am aware, there is no additional risk involved in sharing a drive. Windows will not be able to see the contents of your Linux drive or partition, unless you install additional software. Shared storage partitions. If Windows goes into hibernation, and another OS makes changes to the shared partition, Windows will tend to undo the changes when it is resumed. I recommend either external storage, or disabling hibernation on Windows, or both.
This is new with Windows 8. Both operating systems need to be installed using the same one. You can find a much more in-depth explanation here. Though the installer puts names next to bootable partitions it does help to find other partitions that belong to that specific OS like a D: drive will be sda2 on sda where sda1 is the OS for Windows or db2 is a partition for sdb where sdb1 is the root for Ubuntu.
I myself though would install the bootable partitions ie. The best thing to do is make regular backups of your important data.
If you do that you will only have minor problems. There is absolutely no risk with keeping two operating systems on the same disk device. You can mess with another system partition as long as the disk device with that partition is accesible, putting it on separate physical device doesn't make it safer nor less safe in any way. If you have two hard drives, then installing Windows on one and Ubuntu or any other OS on the other is the most convenient.
If only 3 Primary partitions are defined, create an extended partition and install Ubuntu there. Assuming Windows consumes your entire first hard drive, then you must resize those Windows partitions. There is a sense of security when installing the second OS on a separate hard drive.
With two hard drives, you can just slip the primary one out in the case of a laptop or disconnect the power for a desktop. Now you know that you are not going to accidentally corrupt your main OS while installing the other. For the truly paranoid, you can do the same when upgrading to newer versions. My machine supports four hard drives; so I run Windows 7 on the primary and Ubuntu on the second.
If I press the power button and walk away, then it boots from the primary disk unattended. Another option to consider is to use a virtual machine.
One comment about redundancy - if you plan to set up any kind of disk redundancy mirroring or RAID-5 striping you need to have hard drives of close to the same size to avoid wasting space the system will use the size of the smallest drive.
A hardware approach is much more reliable and performs better than a simple software-based solution. You MUST back up any data you do not want to lose! From a strict system point of view, it is exactly the same Correctly configured partitions are perfectly safe to use and you will never inadvertantly erase date in one partition while working on another one - be they under same OS or not. If you configure them by hand hacking the Master Boot Record with low level tools But if you use high level tools to resize partitions and create next, you should not get into trouble.
As you asked for a safer way, my advice would be to split both disks with one Windows partition and one or more Ubuntu ones on each.
