Kickstart installations offer a means to automate the installation process, either partially or fully. Kickstart files contain answers to all questions normally asked by the installation program, such as what time zone you want the system to use, how the drives should be partitioned, or which packages should be installed. This DVD ISO image can be burned to an optical disk, or we can create a USB thumb drive from it. To make a bootable CentOS seven USB thumb drive using Windows, we can use Win32 Disk Imager.

• Centos Format Usb Drive

So i just brought a 128GB sandisk ultra usb 3.0 because as a computer tec im tired of fumbling through my tons of usb drivers to do a job., i want my windows installers & Linux, bookable tools and such all in one usb. So i looked into multibooting usbs and came across many tools, one being SARDU. But i need a hybird UEFI/MBR boot and my laptop doesn't support uefi & legacy simultaneously only one or the other. So using SARDU i cant see or boot from the usb unless i switch bios to legacy mode, works well because i see and can boot from all of what i have windows installers and linux distros but i have to keep switching back and forth between legacy and uefi. I was wondering if i can make the usb primarily Uefi bootable BUT also bootable for a old MBR if needed.

Hi thereIf you are creating either Windows or Linux install media then an MBR / UEFI system is created anyway and at boot you can choose to load the UEFI or MBR version.For windows 10 use the media creation tool directly - when prompted choose USB rather than ISO.For Linux builds most distros come in.ISO format - simply use RUFUS to create a bootable USB. The system will create a 'Hybrid' UEFI / MBR boot system unless you specifically choose MBR or UEFI.

At boot time the boot menu (at least on my laptop) will show MBR and UEFI as different boot selections.If you partition your USB stick into two partitions then you can have a Windows / Linux install system.Get into cmd mode (administrator) and use DISKPART to create 2 partitions on your USB (or even 3). What I'd recommend is say 1 partition for a Windows install system, 1 partition for a Linux install system and 1 partition for a Macrium reflect rescue system.If you are feeling really adventurous (and with 128 GB it should be possible) create 4 partitions and have a Linux LIVE CD on the 4th partition.4 Partitions are the max on the USB.They all need to be PRIMARY partitions.Cheersjimbo.

It's a bit more subtle than that.When you use the hybrid mode, it is for pcs which support csm legacy bios as well as uefi.It creates an mbr partitioned usb disk, but allows to install OS on a GPT drive for when using UEFI, or on an MBR drive when using legacy bios.The subtle point is the PC has to be capable of supporting both legacy bios and UEFI for this to work, and PC has to be put into legacy bios mode (or be able to autodetect mode e.g. If it sees an mbr usb, it chooses legacy bios).If the PC does not support legacy bios mode eg.

Tablets/hybrids often only support UEFI, then the usb stick has to be setup in gpt format for 64bit installs of UEFI at least (not sure about special case 32bit UEFI but these require special bootloaders anyway).So it is not 100% possible to have an all purpose USB stick.

Managing storage devices - whether they are internal hard drives, SSDs, PCIe SSDs, or external USB devices - is always a tricky task. With a tiny mistake, you may lose data or wrongly format your drive in a way that can lead to data corruption. In this article, I will talk about some of the basics of storage devices on Linux. The article is aimed at beginners and new users of Linux.There are many graphics tools to manage your hard drive. If you happen to use Gnome, then the Disks tool is quite useful.

Centos Format Usb Drive

However, every once in a while I come across issues where it throws errors and fails to format a drive. I prefer to use the command line, as it’s much easier and fail safe. How to find what is connected or plugged to your systemUsing ‘lsblk’ is the simplest and easiest way to find all block devices connected to your system. As you can see, the lsblk command is showing me my SSD ‘sda’ where Linux Mint 18.1 is installed, ‘sdb’ is a USB Flash Drive, and ‘sdc’ is 1TB internal hard drive.

Understanding the lsblk output. Swapnil BhartiyaIn the figure above, the NAME column gives out the name of the device (it’s not consistent and can change based on which device was mounted first). ‘sda’, ‘sdb’, ‘sdc’ etc.

Are the block device names and ‘sda1’, ‘sda2’. Denote the partitions on each device. MAJ:MIN denotes the major and minor device number. RM tells whether the device is removable, and in this example, you can see that the USB drive ‘sdb’ is a removable device.Obviously, the SIZE column tells about usable storage space on the device. RO tells whether the device is read only, such as a DVD drive or write protected Flash drive.

TYPE tells whether it’s a disk or partition, and you can see that block device name with numbers ‘sda1, sda2’ are marked as partitions. The last column tells about the mount point.The lsblk command is capable of giving out more information about storage devices, but we are keeping our focus on formatting a device. Format a drive completely with a brand new partition tableThere is no dearth of quality tools in the Linux world, and we tend to use the ones we like. In this tutorial, I am using ‘parted’ as it’s easy to use and can handle both MBR and GPT partitioning tables, but feel free to use your favorite partitioning tool. I will be formatting a 3.8GB USB flash drive. The procedure can be used on any storage device, external or internal. Sudo parted /dev/sdbDoublecheck to make sure to add the block device you want to format; otherwise, parted will run on ‘sda’ or the drive where your OS is installed and you may end up with a broken system.

The tool is extremely powerful and choosing the wrong device may lead to valuable data loss, so please use caution while formatting your drives.After entering the password, you will notice (parted) added, which means you are now inside the parted utility.Now we have to create a new partition table. There is good old MBR (master boot record) and newer GPT (guid partition table). Comparison between the two is beyond the scope of this story. In this example, we will use MBR. (parted) mklabel msdosHere ‘mklabel’ creates the partition table and ‘msdos’ will use MBR.

Now we can create partitions. This is the basic format of the command: (parted) mkpart ‘type of partition’ ‘file system’ start endIf I want to use all the space and create one big partition I will run this command: (parted) mkpart primary ext4 1MiB 100%Here 100% means it will use all the available space. But if I want to create more than one partition, I will run this command: (parted) mkpart primary ext4 1MiB 2GBHere it will create a partition with 2GB storage. Next, we’ll create another partition, but because we already have one partition, the end point of previous partition is now the starting point of the next partition. (parted) mkpart primary ext4 2GB 5GBThis command will create a second partition of 3GB.

If you want to create one more partition for the remaining space, you know the end point and the start point: (parted) mkpart primary ext4 5GB 100%You can replace ‘ext4’ with desired file type: ntfs, vfat, btrfsTo see how the partitioning has worked, run the print command: (parted) printIt will display the partitions you created. If everything looks as expected, you can exit the partitioning tool by typing ‘quit’: (parted) quitRunning the lsblk command will show the newly created partitions. We need to now format these partitions before we mount and use them. In my machine, there are now three partitions on sdb: sdb1, sdb2, sdb3. We will format each with ext4. Sudo mkfs.ext4 /dev/sdb1Repeat the same step for each drive - just change the block device name and number.Now, your drives are formatted.

If it's an external drive like a USB drive, just unplug and plug it to mount it.Learn more about Linux through the free course from The Linux Foundation and edX. Bhartiya,Excellent post. I have two questions for you: 1- sudo mkfs.ext4 /dev/sdb1 this is correct, Repeat the same step for each drive - just change the block device name and number. I saw an error in this explanation, this practice is only related with the block device represented by sdb, then you must have written for better comprehension of the this practice this: Repeat the same step for each partition - just change the number. I know if you were talking about drives in general, then, it is understandable, but it is not the case. 2- (parted) mkpart primary ext4 1MiB 2GB in this case I note that the first partition begin at 1MiB, why? And what about the rest?

I mean, why not begin at the lowest possible space of the drive? Thanks for the posting.
