RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:

The system disk partition type displays as "Microsoft basic data" in RHEL guests on EC2.

[root@ip-172-31-8-133 ~]# fdisk -l
...
#         Start          End    Size  Type            Name
 1         2048         4095      1M  BIOS boot parti
 2         4096     41943006     20G  Microsoft basic


Version-Release number of selected component (if applicable):
RHEL7.4

How reproducible:
100%

Steps to Reproduce:

1. Start a RHEL7.4 instance on EC2.
2. Connect the instance and check the partition type of the system disk with "sudo fdisk -l" command.

Actual results:
The Partition type is "Microsoft basic data" as default.

Expected results:
The Partition type should be "Linux filesystem".

Additional info:
1. The default partition type is "Microsoft basic data" if using "parted" command to manipulate disk partitions.
   We can see from the ks file "original-ks.cfg" in the instance that we use parted command during building the image, so please change the partition type after manipulating disk partitions or using fdisk to make the partitions.
2. I checked Amazon Linux, the partition type is "Linux filesystem".
